OPEnumerable

This defines some methods on NSObject that are applicable only to objects conforming to the NSFastEnumeration protocol. These methods are very similar to the ones defined in Ruby's Enumerable module, and fully blocked based. For example, to select a subarray one can do:

NSArray *a = @[ @1, @1, @2, @3, @5, @8 ];
[a select:^(id obj){
  return [obj compare:@4] == NSOrderedAscending;
}];
//=> @[ @1, @1, @2, @3 ]

Another project doing something similar is BlocksKit, but the usage of A2DynamicDelegate scares the crap out of me, so I decided to re-implement most of the methods more directly, and more simply.

##Installation

We love CocoaPods, so we recommend you use it.
