Introduction to Simile

Here's a pdf document which I'm going to use as the basis of a practical class to introduce Simile and how it can be used to develop and analyse a model. It is aimed at undergraduate biology/ecology students whoc will have little if any programming experience and even less mathematics.

This is the first time I've written anything like this. If people see potential pitfalls in the approach or ways to improve the description to make it clearer then I'd like to hear about it.
