Class for computing sensor ground coordinates.
The sensor class allows for the computation of parameters related to orbiting instruments. In particular, a time and look direction can be set and from those the ground coordinate (latitude/longitude) along with phase, incidence, and emission angles can be computed. Likewise, a ground point can be set and look direction can be computed. This class is derived from the Spice class.
An important capability of this class is the ability to use a surface model other than an ellipsoid when intersecting the look direction of the sensor with the planetary body. This allows for the generation of othrorectified products. The file containing the surface model is a cube and is obtained from the labels in the follow form:
2003-05-16 Stuart Sides - Modified schema from astrogeology... isis.astrogeology...

2004-02-23 Jeff Anderson - Fixed two bugs in the handling of DEMs. Used universal lat/lon when appropriate and the radius needed to be converted to km when read from the DEM file.
2005-02-15 Elizabeth Ribelin - Modified file to support Doxygen documentation
2005-02-24 Jeff Anderson - Added SlantDistance method and made the constructor ignore the ElevationModel keyword if it is null

2009-02-06 Debbie A. Cook - Changed the tolerance back to 1e-6 (mm)

2009-09-23 Tracie Sucharski - Convert negative longitudes returned by reclat in SetLookDirection.
2010-09-15 Janet Barrett - Modified the SetLookDirection method to use a new algorithm for finding the intersection of a ray with the DEM. This was required to take care of problems that were encountered at the poles of global DEM files. The algorithm that is being used was taken from "Intersection between spacecraft viewing vectors and digital elevation models" by N.A. Teanby.
2010-11-09 Eric Hyer - moved some private members to protected section for Camera
2010-12-07 Steven Lambright - Added LocalRadius(lat,lon) and removed a sqrt from SetLookDirection
2011-01-26 Steven Lambright - The LocalRadius methods now return Distance objects and added a LocalRadius method that uses the Latitude and Longitude classes.
2011-02-08 Jeannie Walldren - Added method parameter documentation.
2011-02-09 Steven Lambright & Debbie Cook - Refactored heavily to use Latitude, Longitude, SurfacePoint, and iTime where applicable. Optimized SetLookDirection. These changes were meant primarily for readability and reducing error-proneness of the code.
2011-03-28 Janet Barrett - Fixed the SetLookDirection routine so that it checks to make sure that the projection of the DEM is in an Equatorial cylindrical projection before using the new ray tracing routine. The check for this was moved when other code was added. This was causing a problem with footprintinit.
2011-05-03 Jeannie Walldren - Added Isis Disclaimer to files.
2011-05-25 Janet Barrett and Steven Lambright - Moved the ownership of the DEM projection to the DEM cube which is owned by CubeManager.
2011-08-22 Steven Lambright - The DEM cube now uses a UniqueIOCachingAlgorithm(5). This will probably behave better in all cases. Fixes #364
2011-08-16 Jeff Anderson - Fixed a problem with an infinite loop in the ray tracing algorithm. The problem was first exposed when trying to intersect the Vesta DEM on the limb.
2011-12-20 Tracie Sucharski - Added SpacecraftSurfaceVector method which returns the vector between the spacecraft and the surface point in body-fixed.
2012-05-04 Steven Lambright - Re-enabled a safety check in the DemRadius() method which was needed due to Projection not uniformly handling Null inputs. Fixes #807.
2012-07-06 Debbie A. Cook - Updated Spice members to be more compliant with Isis coding standards. References #972.
2012-09-06 Steven Lambright and Stuart Sides - Changed the constructors to take Cube instead of Pvl to prevent redundant parsing. This should eventually be refactored into a CubeLabel or similar object so that an actual cube isn't required in the future, but for now this enables the control net GUI to create a camera from a cube with no dimensions in the label.
2012-10-10 Debbie A. Cook - Moved the functionality related to the shape model into new classes: ShapeModel, EllipsoidShape, DemShape, and EquatorialCylindricalShape. Also modified to use new Target class. References #775 and #1114
2012-10-25 Jeannie Backer - Changed resolution() method to lower camel case. References #1181.
2012-03-04 Tracie Sucharski - Added new method, PixelIfovOffsets, which will return the ifov offsets from the center of the pixel in mm. This is a virtual method and if not implemented in the specific instrument camera, this class will throw an error. References #1604.

This method creates an internal cache of spacecraft and sun positions over a specified time range.
The SPICE kernels are then immediately unloaded. This allows multiple instances of the Spice object to be created as the NAIF toolkit can clash if multiple sets of SPICE kernels are loaded. Note that the cache size is specified as an argument. Therefore, times requested via setTime() which are not directly loaded in the cache will be interpolated. If the instrument position is not cached and cacheSize is greater than 3, the tolerance is passed to the SpicePosition Memcache2HermiteCache() method.
Note: Before this method is called, the private variables m_cacheSize, m_startTime and m_endTime must be set. This is done in the Camera classes using the methods SetCacheSize() and SetStartEndEphemerisTime().
| startTime | Starting ephemeris time to cache |
| endTime | Ending ephemeris time to cache |

Sets the look direction of the spacecraft.
This routine will then attempt to intersect the look direction with the target. If successful you can utilize the methods which return the lat/lon, phase, incidence, etc. This routine returns false if the look direction does not intersect the target.
| v[] | A look vector in camera coordinates. For example, (0,0,1) is usually the look direction out of the boresight of a camera. |
2009-09-23 Tracie Sucharski - Convert negative longitudes returned my reclat.
2010-09-15 Janet Barrett - Modified this method to use a new algorithm for finding the intersection of a ray with the DEM. This was required to take care of problems that were encountered at the poles of global DEM files. The algorithm that is being used was taken from "Intersection between spacecraft viewing vectors and digital elevation models" by N.A. Teanby. This algorithm only works on Equatorial Cylindrical projections. Other projections still use the previous algorithm.
2010-10-26 Janet Barrett - The tolerance value of 1E-5 was too small and was causing a divide by zero error when the current and last intersections were virtually the same. The tolerance was changed to 3E-8 * a (where a is the equatorial radius of the planet we are dealing with).
2011-01-24 Janet Barrett - Got rid of extra loop that wasn't needed for the new ray tracing algorithm.
