consolidated MCvars from 4 modules to 1
consolidate MCvars from 4 modules to 1
Some variable movement to new modules.
Specifically moved "gam" and "alpha", along with other minor changes like spelling in a comment.
'Ak' to modular form
'Eig' to modular form
'xi' to modular form
'binPDF' to modular form
'binBounds' to modular form
'pltEigfwhich', 'pltxiBinswhich', and 'pltCowhich' to modular form
'pltxiBinsnumof', 'pltEigfnumof', and 'pltConumof' to modular form
'binNumof' to modular form
'numEigs' and 'tnumEigs' to modular form.  'tnumEigs' only used once, would like to not have it a global variable, but it is passed by reference to a function that numEigs is passed to.  I would need to actually pass 'numEigs' to that function by reference to get around this.  Maybe worth a change later, but not now.
'numSlice' to modular form
'levsrefEig' to modular form
'mostinBin' to modular form
'Corrnumpoints' to modular form
'binSmallBound' to modular form
'binLargeBound' to modular form
'sigave' to modular form
'totLength' to modular form
