Integrate Tenjin using a decorator
This provides basic [Tenjin](http://www.kuwata-lab.com/tenjin/) integration, using a decorator. Tenjin is a blazingly fast templating system, the fastest pure-python system available. For usage and configuration, see the example in the code. I modeled this after Robert Thomson's code for Mako integration.
