Merge commit 'c391883ea8535453b1e9522b7182f64f4cb84f72' as 'forem'
deleted and undid the command rails g forem:views. Views are now rendered from the source and hopefully the models and controllers too. that way we can keep edits to forem logically separate from edits to smartEDU
changed the post views to include embedded youtube. to 1) css of the embedded youtube is now hard coded and its style needs to be changed.
