// Description: 
//       A wrapper class which can take inputs from build task and call the underneath
//       MarkupCompiler, CompilationUnit and other related types to do the real 
//       compilation work.
//       This wrapper runs in the same Appdomain as MarkupCompiler, CompilationUnit,
//
//       It miminizes the communication between two domains among the build tasks and 
//       the real compiler classes.
