FIX for CRAN - reduce CPU use in test cases

Dear maintainer,

your package MSToolkit does not comply with the CRAN policies:

In your tests, you make use of as many (virtual) CPU cores as available in the current machine, i.e. with 32 parallel processes in the unit tests for the most recent Windows check machine.

This does not make any sense and wastes CRAN resources (and for some other reasons cause that the package fails the Windows checks rather frequently).

Please follow the CRAN policies and do not use more than 2 processes!

We expect an update rather quickly. It took me quite soem time to investigate the problem since you are using some obfuscating unit check framework.

Best,
Uwe Ligges

We should explicitly use grid = FALSE option in analyzeData( ) for testing / example cases to ensure that we don't hog CPUs on CRAN test servers.

Line 240 in analyzeData function checks for number of cores and limits to 2 if on CRAN(?) Presumably this isn't working though?
