Enumerable#nest &compare

nest is an inverse for Array#flatten. (Well, actually only a right inverse since flatten is not injective.) You give it a proc that calculates the depth of each item, and it returns a nesting of arrays in which each item has the desired depth. It can be used to parse strings with Python-like indentation syntax, but it isn't limited to strings.

The main improvement in this version is that the compare block can return a lower value for an element after the first, with the expected effect. See the first example at the end of the source file.
