dswitkin da4f56b022 Fixed some code which was ignoring the result of MonochromeBitmapSource calls, which may work in some cases but isn't legal and failed and in some experiments.

dswitkin b613112615 Rewrote BitMatrix to allow rectangular 2D arrays, and so that every row begins with a new int, which makes it fast to copy out rows into BitArrays. This will be the basis of the upcoming bitmap refactoring for 1D Readers.

dswitkin 7fec06465a Continuing with the x, y coordinate push, BitMatrix is now standardized. I also converted DataMask back to i, j for now to be consistent with the rest of the QR module, and made sure all the tests still pass.

dswitkin 5f2b64ee50 Used IntelliJ's amazing refactoring functions to change the argument ordering of ByteMatrix. I want to standardize this across ZXing: the first component should always be horizontal and the second vertical, whether supplying an x, y point or a width, height pair. Also, we should always use x and y as variables with x being the horizontal component to avoid confusion.

dswitkin 9f509172b6 Wrote a quick command line app to calculate how many total images are passing our blackbox unit tests. This could use some improvement but it's a start.

dswitkin 1da9bd60b3 Added a new blackbox test with extreme shadows and highlights. We do pretty poorly on this, but I've been experimenting with local thresholding algorithms which are a night and day improvement. 
Also made the ImageConverter app ignore some kinds of files.

dswitkin c07fad6410 Created a new QR blackbox test with difficult exposures, mostly self-shadowing cases. We only get 34 out of 120 tests, which is about what I expected. To fix these we will have to move away from a global black point and towards a more sophisticated local thresholding algorithm.

dswitkin 51ade2ca96 Added better logging for our blackbox tests. It now displays the number of images which passes per test out of the total, and the percentage. It also warns when a blackbox test is too lax (i.e. we've made decoding improvements but haven't raised the high water mark).

dswitkin e19e9a83f6 I moved a chunk of the histogram/black point code out of BaseMonochromeBitmapSource and into BlackPointEstimator which makes a lot more sense. Unfortunately I had to expose three new methods and touch a bunch of files. But I did manage to reuse an array on subsequent calls, which was being allocated on every row scanned, so that might be a bit faster. It will also be easier to convert this code to JNI in the future if we want to, and/or do more advanced thresholding.
