Added Mex for SimpleFlow

[12dmodel]

Added mex for simple flow algorithm. I was able to compile and run on ubuntu, with result attached:

I just want to point out that the function is already exposed in the master branch: https://github.com/kyamagu/mexopencv/blob/master/opencv_contrib/src/+cv/calcOpticalFlowSF.cpp (as well as the M-docs and unit test).

It should be easy to backport it to the v2.4 branch with minor changes; I believe it was under the "video" module in 2.x before getting moved to "optflow" contrib module in 3.x.

@12dmodel Thanks for your PR. As @amroamroamro points out, there is already the same function in the master branch (for OpenCV 3.x). Can you compare them and check if you are able to backport so that we do not have two versions of the same function across branches?

Will do

@kyamagu
about the failing CI checks:

• in Travis, you could go to the settings page, and set the option "Build only if .travis.yml is present" to ON. That way a build wont be triggered on branches without the .travis.yml file (like v2.4 and so on).
• similarly for AppVeyor, there's a checkbox titled "Skip branches without appveyor.yml" in the settings page

Changing these options in the web UI is the only way to skip building the other branches without having to create a dummy yml file in every branch.

@amroamroamro Right, just updated the settings
