Visibility function expects diameter, not radius.
Added code to save FITS image of the model.
Switched all values to doubles.
Switched all values to doubles.
Added FITS reading routine. It is not a good solution though.
Modified uniform disk test to decrease the impact of pixel alignment issues. Changed unit test threshold to 1E-4 to better match interferometric expectations.
Added Uniform Disk unit tests for OpenCL kernels. Modified UV spiral generation code to include a point near zero.
Changed DFT unit tests to be based on the difference over sum ratio (at a 2 percent level) and 1 degree of phase error.
Modified kernel to encourage shared load operation.
