v0.2.1

This PR:

• fixes up a lot of the project's documentation
• changes CashCash's behavior a bit so that instanceof will return true/false when doing something like… CashCash('body') instanceof CashCash

Useful if you ever need to check whether or not a variable is a, um… cashpile.

v0.1.1

Fixing some publication issues resulting in a mismatch between tags and bower.json version number. No code changes.

v0.1.0

Initial release of CashCash!
