CVS commit by netterfield: 

-Clean up histogram auto-binning - put it all in one place
-add command line equations in main
-some (minor) cleanups to main
-fix ref-counting bugs for command line objects:
	???Ptr were used for some temporary variables which don't go
	out of scope before app.exec(), so the reference stays forever.
	One could
		i) make sure they go out of scope
		ii) make sure they are set to zero before app.exec
		iii) use ???* instead of ???Ptr for temporary variables.
	I have chosen iii
