First check in with workable OSUFlowVTK
trim
solves graphics computation issue
clean up cmake
add vtkOSUFlow and example
vtkOSUFlow first version
StreamlineSimpleVTKPipeline works
Create VectorFieldVTK
StreamlineSimpleVTKPipelineWithLineWidget.cpp works now
StraemlineRender examples works
add readme
added verification: compareStreamline.cpp
Openmp used in Streamline.C
Added a switch in cmakefile
