Objectives in conditions

Model conditions now store objective functions and directions

0.0.3: Merge pull request #18 from SBRCNottingham/develop

Added gsmodutils.utils.design_annoation decorator for annotating python based designs.
Fixed GsmodutilsModel.save_model for sbml models (it used to save it as a matlab).

Changes to test framework

The test framework has undergone a significant redesign in this version, though command line and programmatic APIs are maintained with the tester class.

Users can now do a model.run_tests() on models loaded into memory that have changes from the filesystem version.

Also minor bugs like cleaning up documentation and adding the rst format for pypi.

First release
