From Matthew Strait:
Wraps very long lines used for HTML documentation
Fixes grammar/typo in DrawNormalized output
Fixes grammar in Chi2test output
Switches Chi2test output to refer to "h1" and "h2" instead of "Hist1" and "Hist2" to more closely match the names used in the code, and therefore other parts of the documentation.
Removes a few extra spaces and things like that.
