/**
* Provides the ability to set contraints against a properties of a class. Constraints can either be
* set via the property setters or via the <pre>applyConstraint(String constraintName, Object constrainingValue)</pre>
* in combination with a constraint constant. Example:
*
* <code>
* ...
*
* ConstrainedProperty cp = new ConstrainedProperty(owningClass, propertyName, propertyType);
* if(cp.supportsConstraint( ConstrainedProperty.EMAIL_CONSTRAINT ) ) {
* cp.applyConstraint( ConstrainedProperty.EMAIL_CONSTRAINT, new Boolean(true) );
* }
* </code>
*
* Alternatively constraints can be applied directly using the java bean getters/setters if a static (as oposed to dynamic)
* approach to constraint creation is possible:
*
* <code>
* cp.setEmail(true)
* </code>
