data: name hierarchy refactoring

* replaced typenames (which have been stored as single sting where "::" indicated hierarchy levels) by a vector of strings where each element indicates a hierarchy level.
* introduced this change to the Storage method signatures, the ParseFunction and ParseVariable
* this way the SearchIndex creates a node for each level of the hierarchy.
