Provide access to script's compiled instance as dynamic object

[abeham]

If the user adds additional methods to the class that she creates this would make those methods accessible from other operators. For example:

public dynamic Instance {
  get { return CompiledInstance; } // often CompiledInstance is a property that returns the compiled instance or compiles it if it hasn't been already
}

would then allow to write the following exemplary code in an operator

var myResult = (double)ScriptParameter.ActualValue.Instance.MyMethod(5, false);

I would do this in general for all scripts, but at least for the OptimizationSupportScript in the external evaluation plugin.
