FoundationAdditions

Here's a random set of additions to the Foundation (and in some cases Cocoa) framework classes. Some of these are old and out-of-date and likely implemented better elsewhere, so your mileage will definately vary. Where the source code is not copyright by me, I indicate this below and in each header file. For the remainder, the license is described in the LICENSE.md file.

Any bugs or additions, please let me know!
