trying to get escodegen to generate comments from AST
replaces empty lines and prepends all comments
quick save before I branch off and experiment
total rewrite -- I fixed the syntax bug that was messing up the tokens, so now comments are attached!
corrected esprima config options
replaces empty lines with comments, so they'll be preserved
adds second argument to Assertions
works beautifully for all single-line statements, and multiline function calls like asserts.  Still need to deal with multiline strings, single line if statements, etc
removed unneccesary log
updated test.js
