MItAC update

1) created fake spiral data, beginning work on center locating algorithm

2) top-level design appears to match Haber's previous work in 78rpm audio recovery

3) investigation into memory requirements
- please watch http://www.mathworks.com/cmspro/req11290.html?eventid=32518 which describes how to handle large datasets in MATLAB
- 32-bit machine - max 2-3GB, MacOS - max 3-4GB, 64-bit Linux - max 16 GB
- need to consider block processing and image downsampling (textscan, memmapfile)
- data storage - convert from double in Vision to integers
- process - trade speed for memory by devectorizing operations, nesting, using pointers rather than copy write operations between functions, useful tool "monitormatlab"
- plotting - need to downsample
