PAT 2.0 - Replace EnergyPlus Example for PAT

The current EnergyPlus example uses ComponentCost:LineItem and also changes the OutputControl:TypeStyle to "InchPound". This is really my fault, but both of these are now bad examples. ComponentCost now exists as an OpenStudio item so isn't a good example for EnergyPlus Measure. More important changing the OutputControl:Type:Style will brake OpenStudio reporting as it also change the tabular SQL data.

Maybe a simple EMS example would be relevant. Make sure the example doesn't just add object, but shows how to alter existing object.
