 # ideas
 
    - make it work in the browser for client side validation
-   - strict mode, dissallowing extra parameters from being passed in
    - dependency property making one parameters existance depend on another
    - more types (phone numbers, credit card, ip address)
    - more filters (camelcase, encode/unencode)
