[Method] allEq [Parameters] Map properties [Purpose] 
A shortcut for requiring several properties to have particular values. The keys of the supplied map are the names of the properties you want to constrain, while the values in the map are the target values each property must equal if an entity is to be included in the query results. The returned Criterion ensures that each named property has the corresponding value.
