Pre-loading example data

[juanfung]

Data used in the examples currently stored under pycge/pycge/data/, and included in MANIFEST.in

Example model definitions and scripts, currently stored under pycge/pycge/examples/, can be loaded as modules; e.g., from pycge.examples.splcge_model_def import SplModelDef.

A user cannot easily access the data. The best option afaik is:

import os, sys
os.path.dirname(sys.modules['pycge'].__file__)+'/data/path_to_data' 

It might be better to automatically load the data when loading the module. For example, by adding the above commands to splcge_model_def.py.

A better solution is to use pkg_resources, included in setuptools: see ResourceManager API, eg:

import pkg_resources
spl_path = pkg_resources.resource_filename('pycge', 'data/splcge_data_dir')

This can be included in splcge.py or another file (or wrapped in a function loaded with pycge).
