Feature: self_and_children

I've got a need to list the parent and it's children and was thinking that there should be a self_and_children feature.

@map7 This feature exists as self_and_descendants, which will return a flat collection of the parent and all of its nested children. You can find the method in question here:

awesome_nested_set/lib/awesome_nested_set/model/relatable.rb

Lines 47 to 51 in 76bfb77

    
           # Returns a collection including itself and all of its nested children 
        
           def self_and_descendants 
        
             # using _left_ for both sides here lets us benefit from an index on that column if one exists 
        
             nested_set_scope.right_of(left).left_of(right) 
        
           end
