Added the pure virtual isItThere method in base class eoParameterLoader

Browse source 
Also made the corresponding isItThere method in eoParser public.
This allows one to test if the user did actually input a given parameter
and thus not to write it in the output if not - as we want the output
of printOn to be "as identical as possible" to the actual user input
