Updating WTDTA1.mo and Renewable Model Base Classes
The updates are as follows: 1) Eliminated intermediate variable in WTDTA1.mo model that was being used to make initial equation T0 = P0; 2) Eliminated start values from realinputs and realoutputs. This was done in all renewable components that had such thing. 3) Fixed one error on the REECB1 model. 4) All renewable test examples are configured to start the default simulation with QFunctionality=4.
