  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
