wxWidgets/samples/typetest/typetest.cpp
Roger Gammans cf6ae2907c Addition at simple wxObject*, support into wxVariant. 
This includes 2 new methods wxVariant::IsValueKindOf() and
wxVariantData::GetValueClassInfo() to allow query of the
wxRTTI data of the variant's data.

Also included is a macro analogues to dynamicCast for fetching
objects out of a wxVariant.

Documentation patches for the above.
