     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.
