* transform_values {|value| ... } -> new_hash
* transform_values -> new_enumerator
*
* Returns a new +Hash+ object; each entry has:
* * A key from +self+.
* * A value provided by the block.
* With a block given, returns a new hash +new_hash+;
* for each pair +key+/+value+ in +self+,
* calls the block with +value+ and captures its return as +new_value+;
* adds to +new_hash+ the entry +key+/+new_value+:
*
* Transform values:
* h = {foo: 0, bar: 1, baz: 2}
* h1 = h.transform_values {|value| value * 100}
* h1 # => {foo: 0, bar: 100, baz: 200}
*
* Returns a new Enumerator if no block given:
* h = {foo: 0, bar: 1, baz: 2}
* e = h.transform_values # => #<Enumerator: {foo: 0, bar: 1, baz: 2}:transform_values>
* h1 = e.each { |value| value * 100}
* h1 # => {foo: 0, bar: 100, baz: 200}
* With no block given, returns a new Enumerator.
