Performance analysis with multiple scenes

[cdeline]

At the moment, performance is run on the entire RadianceObject, which means that a single module type is passed, even if you have multiple scenes with different module types.

Solution:

• Make CECModule an optional property of the ModuleObj. When you run calculatePerformance, loop through sceneNums and check for defined CECModule if it’s not passed into calculatePerformance. Default to Prism.
