Add dynamic attribute-based selectors. Ex:
[{:name=>'Guy',:last_name=>'Shmuely'}, {:name=>'Jack',:last_name=>'Sperow'}].find_by_name_and_last_name('Guy','Shmuely') => [{:name=>'Guy',:last_name=>'Shmuely'}] [{:name=>'Guy',:last_name=>'Shmuely',:age=>25}, {:name=>'Jack',:last_name=>'Sperow'}, {:name=>'Roobin'}].collect_name_and_last_name => [['Guy','Shmuely'],['Jack','Sperow'],['Roobin',nil]]
Calls superclass method
