Moved one macro from macro.sas to own file
Installed StatRep package, added its macro file
Edited text sent to log in gee.sas
Moved macro out of macro.sas file
Updated readme.txt file for DocItOut
Updated README, merged readme to work with pdf + github

A few commits back I created two READMEs, one for github and one for
pdf. However, that is not ideal at all. So I combined them, moved the
pdf YAML header into a hidden file, and created a Makefile to make the
pdf properly while keeping the md in the GitHub format.
Updated html documentation
Updated TODO, added comment header to gitignore
