Point release 0.1.1
The main improvement is the addition of client-side rendering.

Also:
- Server
 * ColorRamp is now an interface with various implementations, for easier extension
 * Ability to serve out tiles as .jpg, .png, or .json - just change the extension in the request URL.
 * The server will now honor server requests without a previous layer request, but of course only with defalts for all parameters which would be specified with the layer request.
- Client
 * Porting of pyramids and tile iterator to the client side for ease of use there.
Merge branch 'release/0.1.1'
