## Test Whether it is an Absolute Unit

### Description

Test Whether it is an Absolute Unit

### Usage

    is_abs_unit(u)

### Arguments

`u` | A `unit` object.

### Details

Besides the normal absolute units (e.g. "mm", "inches"), this function simply assumes `grob` objects as absolute units.

For a complex unit which is combination of different units, it is absolute only if all units included are absolute units.
