Have criteria projections return a map

CriteriaProjections.groovy

import org.hibernate.criterion.CriteriaSpecification

BlogEntry.withCriteria {
  maxResults 5
  resultTransformer(CriteriaSpecification.ALIAS_TO_ENTITY_MAP)
  projections {
    count('id', 'total')
    groupProperty('author', 'author')
  }      
}  

// And another example
def importedDate = AwesomeDomain.withCriteria(uniqueResult: true) {
    eq "propertyName1", someValue
    eq "propertyName2", someValue
    projections {
        property "propertyName1", "propertyName1"
    }
}
