Implemented the LSTDQExact method
Implemented tests on the learning function for the Chain domain
Added tests for LSPI on the pendulum domain
Added a test to verify that LSTDQExact and LSTDQ give the same answers.
Tweaks to LSPI algorithm to prevent singularities with small sample amounts.
Changed test syntax to proper double equality testing
Added a program that will give computation time for the different LSTDQ methods
