add comment support: convert matlab to python single-line comments by replacing % by #
new cmd line opt: strip comments
ignore .egg-info
add whitespace between operators, commas, towards PEP8 conformance of generated code
add .rest extension to readme for proper github parsing
replace any windows \r terminating comments
treat comments and code on same line, avoid SEMI consuming comments after it

- bugfix: code and comments on same line need alterations of parsing syntax. Instead: preprocess by replacing % with \n% to place all comments on their own line
- SEMI consumed any comments following it Remove %... from its regexp
- note: %%... becomes #\n#... which might be taken care in the future, e.g., converting it to """..."""
