Here are some extensions to the Hash class used by Locana.

Returns a new Hash including the union of self and h. This allows you to do things like:

  hash = {:my_value=>4}
  hash + {:my_other_value=>10}  => {:my_value=>4, :my_other_value=>10}

• h - a Hash of values to add to self.

Returns a new Hash with elements from h removed from self. This allows you to do things like:

  hash = {:my_value=>4, :another=>'test'}
  hash - {:another=>1}  => {:my_value=>4}

• h - a Hash of values to subtract from self.

Returns an array of the keys after the keys have been converted to strings.
