Imported cakePHP initial app structure
Created first model: Post with a single wrapper method that returns all posts ids and titles, and its fixture and test case
Added getSinglePost method and corresponding test case.
FIXME: TODO: test case fails because of the created and updated fields are not the same as defined in the fixture (dunno why!!)
Fixed last bug:
		  - extending from PHPUnit_Framework_TestCase instead of Cake_TestCase resulted in using production db
		  - test model database was not overriden as $useDbConfig was not set in fixture class

Created addPost method for Post model and its test method
