New version of otbSpatialisation, change in VectorDataToLabelMapWithAttributesFilter (automatic computation mode). Streaming problem in ImageSimulationMethod

Add a C++ version of PROSAIL. Modify otbAtmosphericCorrectionsRSRSVMClassifier to first compute the reduce spectral Response of the sat and then apply atmospheric effects

add ctest for otbReduceSpectralResponseSVMClassifier and cmake variables for spectrum directory and rsr directory

add ctest for otbReduceSpectralResponseSVMClassifier and cmake variables for spectrum directory and rsr directory

Example of 6S chain /do not work now; need to change atmospectralresponse to reduce the size of the filter function

ENH: convert otbspectralresponse to filterfunctionvalues(6S) and add otbAtmosphericCorrectionsSpectralResponse(need to add the 6S procees to this class

ENH:add randnir indice vegetation class with test OK / add surfacereflectancetoreflectance base class(not OK now)
