Add Integer Keys?

[crazyrabbitLTC]

=First off, great library!

I wanted to ask, do you think it's possible to add integers as keys an option? I like the addresses and bytes32 but I have a use case where Integers seem like a better key option.

Say for example you want to use uint256 as keys, you could simply replace all occurances of bytes32 with uint in the library.
