New posting functionality

Posting works. Pulling from the DB works. Tags do not work by design.
That, a few more access methods, and polymorphic querying are next.
Added Accessors and Mutators

These methods return the protected variables we need to display the
posts in the newsfeed. The mutators will eventually alllow us to edit
posts, but are not fully implemented. We still need to implement the
queries that will connect to the DB and modify the posts's information
based on which mutator gets chosen. We may just choose to make one
master mutator that changes all fields/variables at once, but there are
some possible concerns with that.
Tags working

Changed the create functions to include making tags, changed the PHP
create functions to pull tags from the DB and add them to the PHP post
object as an array.
New post functionality has a draw function

Just what it says.
