redesign of classify, add categorize
* classify should take any arity-1 mapper including hash or array
* classify always assumes 1 return value from the mapper
* a function that assumes a list value from the mapper is needed
* that function is called categorize, a bigger name for a slower function
(it is less efficient than classify since it must loop over mapper values)
* both classify and categorize now return a hash, since it's stupid to create
a hash, return its pairs, only to recreate an identical hash outside,
and it's trivial to extract the pairs from a hash if you need them.
