log in page functional. If logged in, will redirect to /blog/ page. Currently, no restrictions.
going to /blog/posts logged in will work, else redirect. first step to restricting access to only "followers".
 channels are now limited to those who are following. public is viewable to everyone
public/private now works, wrote tests for public/private viewing of channels. will have to go back and clean up code

made the smaller changes such as = spacing and moving imports to the top as suggested.
fixed the tests for what is seen on the index page

 changed from PostManager to PostQuerySet, fixed some tests from "assert x not in y" to "assertNotContains(y, x)" for checking content of page. removed some unused imports.
