cv::Mat to CDenseFeature conversion Factory and vice versa.

I have made a factory which directly converts any cvMat object into any(required) type of CDenseFeatures. 
and  CDenseFeature<float64_t> into the required type of cvMat (any)
is this actually a bad copy-paste?
do you know what `-DTRAVIS_DISABLE_UNIT_TESTS=ON -DTRAVIS_DISABLE_LIBSHOGUN_TESTS=ON` stands for?
  * `-DTRAVIS_DISABLE_UNIT_TESTS=ON` disables gtest based unit tests, hence you don't have unit testing....
  * `-DTRAVIS_DISABLE_LIBSHOGUN_TESTS=ON` disables the building and running libshogun (c++) based examples.
