// {{entity}} sanitizer

// idioms:
//     
//     var instance = Model.instance(id);
//     
//     // this will call EntitySanitizer.sanitize("fieldA",valueA) automatically
//     instance.fieldA = valueA;
//     
//     instance.validate();
//     
//     instance.save();
//     
// 
// usage:
//     
//     * instance data comming from outside should be automatically sanitized
//     
//     var ModelSanitizerFactory = require('MyAppImpl').getModelSanitizerFactory();
//     var EntitySanitizer = ModelSanitizerFactory.getSanitizer('Segment/Entity');

//         requestCommit.apply(this);
