[core] Add new type of ChoiceParam that changes dynamically according to other values

Browse source 
Add new type of ChoiceParam that changes dynamically according to other
values.

When value of an attribute is changed onAttributeChanged is called,
allowing to have unique reaction within node files.

Also add of callDesc function to be able to have other functions such as
onNodeCreated at creation of node.
