Starting working on adding unit tests to check basic functionality of install.
Reverted previous changes where I commented out the "pre-definition" of some variables in the astro_filter class.

Need to write some tests to make sure this works.
Added some basic unit testing.

The point of these tests is to make sure things are in basic working order. For now, the tests include creating models and doing some very basic functions.
Merge branch 'first-unit-tests', which was for developing some rudimentary unit tests.
