/**
* Parse properties to extract optional model id definitions. The format is as follow:
*
* <p>
*
* <PRE>
* define.model-id.column-id=modelid-noScaler
* define.model-id.modelid-noScaler.exclude=a,b
* define.model-id.modelid-noScaler.exclude.a.argument=scaler-name
* define.model-id.modelid-noScaler.exclude.a.skip=1
* define.model-id.modelid-noScaler.exclude.b.argument=normalizer-name
* define.model-id.modelid-noScaler.exclude.b.skip=1
* </PRE>
*
* These properties would define one new model-id called, to be written in a column called
* modelid-noScaler, which excludes two arguments and one value each from the hashcode modelId
* calculation.
