added preliminary CoffeeScript support (see #23)
-t and -p options now also work w/ coffeescript - closes #23

i.e., you can write examples + benchmarks in coffeescript
updated equality handler patterns to also allow braces and quotes

...this is still not really robust: you could have, e.g., a
string containing spaces on one side of the '==' and it won't
get picked up. unfortunately it isn't as simple as doing
(.*)==(.*) or whatever because there could be a string
*containing* '==' on either side too. of course, i don't really
want to scrap the regex approach because it's nice and simple.

so i'll put some more thought into this...
forgot to include full private namespaces in benchmarks
going to try this again: allowing doclets w/o descriptions
added 'calls' and 'calls asynchronously' example handlers
added support for example handler data property
forgot to add coffee-script to package dependencies (whew!)
