Library usage

var fs = require("fs");

var filename = "path/to/file.c";

# Or, to force the language to be C:
var inv = pieces.inventory(source_code, "c");

TODO

• Tweak regexes, figure out what the continues are and if we need them
• Count newlines, spaces, and tabs (which could be spaces) individually
• Count operators and keywords individually
• Pair up opening and closing tokens, like parens
• More languages
• Allow multiple input files, maybe directories
