Fixed a bug where params.PFmode = true caused incorrect edge detection results.
Updated edge_drawing.py to support the new EDColor feature.
Created a new edge_drawing_demo.cpp for demonstrating the EDColor feature.
Updated ximgproc.bib to include references for EDColor.
Added tests for PFmode and EDColor in test_fld.cpp.
Added CV_WRAP to Params::read and Params::write functions to expose them to Python bindings.
the class NFALUT uses the code from original ED code

* Renamed void edgepreservingFilter to void edgePreservingFilter
This simple detector runs up to two times faster than LSD while achieving
competitive results. Please evaluate the algorithm with samples/fld_lines.cpp

added to the ximgproc module
* New optical flow algorithm, based on PyrLK sparse OF and sparse match
interpolation, is added to the optflow module
