Check nesting depth of parameters

[phdmakk]

We would need means to configure T3Q to report when the depth of nested function/template calls is above a given limit which affects readability, maintainability and the performance of T3Q (estimated impact 10*4^Nesting_Depth).

In addition we would need some reporting for inline templates too, but for this we would also need some criteria regarding complexitiy of allowed inline templates as e.g. calls like "f_Myfunction({v_Element1, v_Element2})" may be acceptable.
