/**
* Test harness whose goal is to simplify the task of writing type-system
* regression test. It provides functionalities to build custom types as well
* as to access the underlying javac's symbol table in order to retrieve
* predefined types. Among the features supported by the harness are: type
* substitution, type containment, subtyping, cast-conversion, assigment
* conversion.
*
* This class is meant to be a common super class for all concrete type test
* classes. A subclass can access the type-factory and the test methods so as
* to write compact tests. An example is reported below:
*
* <pre>
* Type X = fac.TypeVariable();
* Type Y = fac.TypeVariable();
* Type A_X_Y = fac.Class(0, X, Y);
* Type A_Obj_Obj = fac.Class(0,
* predef.objectType,
* predef.objectType);
* checkSameType(A_Obj_Obj, subst(A_X_Y,
* Mapping(X, predef.objectType),
* Mapping(Y, predef.objectType)));
* </pre>
*
* The above code is used to create two class types, namely {@code A<X,Y>} and
* {@code A<Object,Object>} where both {@code X} and {@code Y} are type-variables.
* The code then verifies that {@code [X:=Object,Y:=Object]A<X,Y> == A<Object,Object>}.
