improved arguments management:
now you can compile file to file and directory to directory too.
so you can have a coding three like this:
/scripts
    /bin
    /map
    /tmp (for caching)
    /src
and continuum will compile everything in a separate directory.
(better practice for deployment and packages creation).

improved cache and source maps:
both can have their destination directory, cache files do not contain code (they just serves for their creation timestamp).
changed extensions (.cache, .map) too.

improved coding style.
