f454929d9c PRNG changes: xorshift128+ algorithm, and seeding API. 
- Switched to the extremely fast, while simple and high-quality,
xorshift128+ PRNG algorithm by Sebastiano Vigna in "Further scramblings
of Marsaglia's xorshift generators. CoRR, abs/1402.6246, 2014" (2^128-1
period, passes BigCrush tests). Performance improved by 10% over
random().
- Added an API to allow seeding with a specified seed, rather than using
rand() or random(). This allows deterministic, reproducible results in
tests using our algorithm (although findHomography() does not yet
support passing an entropy source on its own end).

ff2509af56 Fixed printouts in testcase to blame the correct method for a failure. 
Previously, certain test failures by the method RHO would result in an
error blaming RANSAC instead. The fix involves a parameter change to
several functions in test_homography.cpp.

adac8c04bb Converted to C++ style, + bugfixes. 
The code has been refactored in response to feedback on Pull Request

Also, outputZeroH() now also zeroes the inlier set, much like
outputModel().

87c2b8197a Bug fixes in mask output. 
Previously, the output mask of inliers could remain completely
uninitialized. This fix is the first part of a solution.

b90800f0c7 Corrected typo in comment. 
The inverted JtJ does not multiply itself, but rather Jte. Correct this
in the comment.

02124f19e6 Further LevMarq improvements. 
Implemented a damping-parameter choice strategy similar to that
described in http://www2.imm.dtu.dk/documents/ftp/tr99/tr05_99.pdf.
Removed a few debug statements.
Chosen a new starting lambda value, 0.01.
We now actually output the mask of inliers.

ff91af825d LevMarq made semi-functional. 
Replaced the complex rules OpenCV uses to select lambda with a naive but
fast heuristic. It's imperfect but produces good results. It is still
subject to the same problem as OpenCV - namely, on occasion LevMarq will
make a poor result even worse.

68e59d6154 [RHO] Initial commit of RHO algorithm for rapid homography estimation. 
Implements the RHO algorithm as presented in

Paper: Bilaniuk, Olexa, Hamid Bazargani, and Robert Laganiere. "Fast
Target Recognition on Mobile Devices: Revisiting Gaussian Elimination
for the Estimation of Planar Homographies." In Computer Vision and
Pattern Recognition Workshops (CVPRW), 2014 IEEE Conference on, pp.
119-125. IEEE, 2014.

- Complete, heavily documented reference C implementation, as well as
temporarily disabled dirty SSE2 port.
- Enabled tests for RHO in test_homography; Currently these fail
presumably due to too-stringent accuracy requirements.
- Refinement and final refinement are not yet functional; Do not pass
their corresponding flags to RHO.
