     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.

_A_r_g_u_m_e_n_t_s:

      xs: A 'xcmsSet-class' object which contains picked ms1-peaks from

     ...: further arguments to the 'collect' method 

_D_e_t_a_i_l_s:

     After running collect(xFragments,xSet) The peaktable of the
     xcmsFragments includes the ms1Peaks from all experinemts stored in
     a xcmsSet-object. Further it contains the relevant MSn-peaks from
     the xcmsRaw-objects, which were created temporarily with the paths
     in xcmsSet.

_V_a_l_u_e:
