Class CollectableAttribute

source code

Base class for any custom behaving attribute intended to become part of a collection

Derived classes will have specific semantics:
* StateVariable: conditional storage
* Parameter: attribute with validity ranges.
 - ClassifierParameter: specialization to become a part of
   Classifier's params collection
 - KernelParameter: --//-- to become a part of Kernel Classifier's
   kernel_params collection

Those CollectableAttributes are to be groupped into corresponding groups for each class
