Detailed Description
TAO_Constraint_Interpreter will, given a constraint string whose syntax and semantics comply with the trader specification for the constraint language, determine if a CosTrading::Offer meets the constraints.
TAO_Constraint_Interpreter will first build an expression tree representing the constraint expression using Lex and Yacc. Then, using a TAO_Constraint_Validator, it will validate the semantic correctness of the tree. When the evaluate method is invoked with an Offer, the TAO_Constraint_Interpreter will construct an EvaluationVisitor, which will evaluate the tree and decide whether the offer meets the constraints.

This constructor builds an expression tree representing the constraint specified in constraints, and throws an Illegal Constraint exception if the constraint given has syntax errors or semantic errors, such as mismatched types.
