20// We want to support properties, event sources and events sinks through
21// explicit declarations, using templates and specialization to make the
22// effort as painless as possible.
23//
24// This means we have the following domains :
25//
26// - Type Information for categorizing built in types as well as custom types
27// this includes information about enums, their values and names
28// - Type safe value storage : a kind of wxVariant, called right now wxxVariant
29// which will be merged with wxVariant
30// - Property Information and Property Accessors providing access to a class'
31// values and exposed event delegates
32// - Information about event handlers
33// - extended Class Information for accessing all these
