// Class name : CCompiler
// Description : This class is used to encapsulate the operations used in
// compiling a Java source file. This manages all of the table-driven
// parser code produced by flex and bison.
// To use this interface, call the public static member function
// 'CompileValue' which takes in a string and parses it into a list of
// CJavaClassFiles, if possible.
