Summary0023489: Memory leak in TNaming_NamedShape
DescriptionUpon TNaming_NamedShape destruction, internal shape collections do not get freed leading to massive leaks.

The fix will be to add a destructor that will call TNaming_NamedShape::Clear().
Steps To ReproduceSee the enclosed test case.
With the enforced clean up by calling TNaming_NamedShape::Clear(), the real destruction takes place.
TagsNo tags attached.

Additional Draw command <ClearNS Doc Entry> is integrated in CR23489. This command allows to clean NamedShape attribute's data structure if found at the label with the specified Entry.
