Parallel processing in XCMS

XCMS has supported parallel processing for several years now in several processing functions that promise a linear speed-up if run in parallel on multiple input files, like e.g findPeaks() used in the xcmsSet() function, controlled by the nSlave argument.

Several mechanisms were supported, the first one, the Message Passing Interface (MPI) is the most powerful, as it is the standard on big HPC cluster systems.
