Stripped-down example of Multi-layer Perceptron MLP in Theano
"""A stripped-down MLP example, using Theano.
Based on the tutorial here: http://deeplearning.net/tutorial/mlp.html
This example trims away some complexities, and makes it easier to see how Theano works.
Design changes:
* Model compiled in a distinct function, so that symbolic variables are not in run-time scope.
* No classes. Network shown by chained function calls.

Quicker Travis builds that rely on numpy and scipy using Miniconda

For ETS's SKLL project, we found out the hard way that Travis-CI's support for numpy and scipy is pretty abysmal. There are pre-installed versions of numpy for some versions of Python, but those are seriously out of date, and scipy is not there are at all. The two most popular approaches for working around this are to (1) build everything from scratch, or (2) use apt-get to install more recent (but still out of date) versions of numpy and scipy. Both of these approaches lead to longer build times, and with the second approach, you still don't have the most recent versions of anything. To circumvent these issues, we've switched to using Miniconda (Anaconda's lightweight cousin) to install everything.

A template for installing a simple Python package that relies on numpy and scipy using Miniconda is provided below. Since it's a common s
