"""
This is the common settings file, intended to set sane defaults. If you have a
piece of configuration that's dependent on a set of feature flags being set,
then create a function that returns the calculated value based on the value of
FEATURES[...]. Modules that extend this one can change the feature
configuration in an environment specific config file and re-calculate those
values.

We should make a method that calls all these config methods so that you just
make one call at the end of your site-specific dev file to reset all the
dependent variables (like INSTALLED_APPS) for you.

Longer TODO:
1. Right now our treatment of static content in general and in particular
   course-specific static content is haphazard.
2. We should have a more disciplined approach to feature flagging, even if it
   just means that we stick them in a dict called FEATURES.
3. We need to handle configuration for multiple courses. This could be as
   multiple sites, but we do need a way to map their data assets.

When refering to XBlocks, we use the entry-point name. For example,
|   setup(
|       name='xblock-foobar',
|       version='0.1',
|       packages=[
|           'foobar_xblock',
|       ],
|       entry_points={
|           'xblock.v1': [
|               'foobar-block = foobar_xblock:FoobarBlock',
|           #    ^^^^^^^^^^^^ This is the one you want.
|           ]
|       },
