On the 1/11 Metafor Call, I was told that the simulation modifications would not make it into the component tree and that we would have to deal with this ourselves.

Here is one idea

1) Create a tab called model modifications
2) Create a class called model modifications
3) Create a property called hasModelModification
3) Take every mod (name-value) pair concatenate them so that we get

Model Modification: name + value

instance name will have to be esg:model_modification_modelname_simulation_name_#, where # = 1-N
