/**
 * Create a Criteria from filter. If filter is a entity class instance, 
 * return a Criteria with a Example Criterion applied.
 * If not try four options in order:/*from w  w w .ja  va2s.  c  om*/
 * 
 *    1. if there are a filter with name filter.getName() enable it and return criteria
 *  2. if there are a criteria builder with name filter.getName() use it to create Critera.
 *  4. if there are a method named createCritera + filter.getName() invoke it to create Criteria
 *  5. Return a Criteria for this entity class without Criterion applied.
 * 
 * @param filter the filter
