Natan notes

Please note:
1. In KIACryptoSpec.m, I just changed the order of the specs.
2. When KIACrypto.init fails to create keys, it raises an exception, instead of returning nil.
Solved.
I removed the "sendsubviewtoback" and "bringsubviewtofront" and, in the storyboard, I changed the position of QRView to the front of the primary view.
