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