Initial Commit
Created the beginning of a tone app.
Added a ton of new stuff. Built in listening features, along with a fast Fourier transform.
Basic data transmitting works with 8 bits...
Greatly improved stability of data receiving!  It seems to work reliably in the ultrasound range, with 8 frequencies.
Slightly increased the generosity of the standard deviation.
Once again, re-worked the receiving code.  It now raises each number to the 4th power to spread the data out, and then computes ratios to determine valid numbers.
Changed receiving code again... it now uses strange math to produce good results.....
Tomorrow: use STD of the ratios to filter data.
Committing just to save code....
Changed frequency indexing to very generously match nearby frequencies.
Switched to only 4 frequencies, and used manual, log distance scaled frequencies.
Added amplitude adjustment on the transmitting side to boost certain frequencies, and changed standard deviation code.
Decreased the number of indices the code searches for a certain frequency, and changed amplitude adjustment to recognize the device at runtime (and choose the right amplitude adjustment).
Created most of the framework for sending  a stream of data in packets.  We implemented a delimiter tone to distinguish between packets, and implemented collecting of received packet data into an array.
Fixed spelling of deliminator -> delimiter
Implemented very basic data and text transmission!
Implemented processing of packets of data... seems to work well receiving on the iPad, and only somewhat well receiving on the iTouch.  We believe interference patterns caused by the wide speaker on the iPad are making it difficult for the iTouch to detect frequencies.
So much stuff!
Removed tesseract
Changed fallback packet length to detect the closest length to 30, and fixed bug with glitchy audio when re-transmitting.
