Fixed delegation of mixin methods.  Props wpscholar.
Changed name of parent classes from Exo_Main_Base to Exo_Controller_Base.
Registration of the "helper" class _Exo_Meta_Helpers, added so we can isolate the apply_meta_prefix() functionality.
Added in some marketing notes about the project.
Changed base model to use generic ‘object’ for internal use rather than ‘post’.
Improved/corrected comments and code formatting.
Created a model that can (hopefully) be used for generic custom posts for those who are not comfortable creating their own subclassed models.
Fixed the name of class in PHPDoc comment
Moved to using dash as filename prefix for those classes that are prefixed with underscore.
Moved the logic from theme_dir/uri, wp_is_loaded and runmodes to Exo_Controller_Base in class-controller-base.php.
Implemented a basic base model parent class for models that represent posts.
Removed register_autoload_subdir() and am just going to use register_autoload_dir() instead, to simplify explaining usage.
Miscellaneous changes before commit.
Added a version number.
