new features:
lots of work on the satellite image stereo correlation tools including a new camera calibration tool for GOES images
use a hidden folder to store all the temp files that DICe creates
enable drawing epipolar line in stereo mode to do a rough check of calibration
bug fixes:
neighbor subset searching for strain in stereo full-field is now using the correct subset coordinates instead of model coordinates (this was a major bug in the stereo full-field tools and gave different results for stereo vs 2d dic on some specimens)
warning instead of fail for poor distortion model performance in camera calibration
.JPG and .jpg are both valid file extensions now
GlobalPixelShift test should be passing on linux again
make c++11 flags missing a CMake warning, not error
