// A class that can carry around a clang ASTContext and a opaque clang
// QualType. A clang::QualType can be easily reconstructed from an
// opaque clang type and often the ASTContext is needed when doing
// various type related tasks, so this class allows both items to travel
// in a single very lightweight class that can be used. There are many
// static equivalents of the member functions that allow the ASTContext
// and the opaque clang QualType to be specified for ease of use and
// to avoid code duplication.
