Added the CorrectionInfo and Correctable headers to the repo.

Which corrections are being read in and which are being applied are in flux

Instead of repushing things in the main loop it now uses the overloaded
assignment operator in lenda event.
Copied over the filter from the gamma builder
Added more to input manager.  Help opition and a new print method to show all values of
the variables in the maps
Changed name to Corrector instead of NeutronCorrector
