## Constructor for xcmsFragments objects which holds Tandem MS peaks

### Description

EXPERIMANTAL FEATURE

xcmsFragments is an object similar to xcmsSet, which holds peaks picked (or collected) from one or several xcmsRaw objects.

There are still discussions going on about the exact API for MS$^n$ data, so this is likely to change in the future. The code is not yet pipeline-ified.
