Fixed baseline and densitiy in cudaprob

[KSkwarczynski]

With CUDAProb it is being set at constructor level

MaCh3/samplePDF/samplePDFFDBase.cpp

Lines 940 to 941 in 29484d5

	MCSamples[iSample].Oscillator->setPathLength(PathLength);
	MCSamples[iSample].Oscillator->setDensity(Density);

while in prob3++ etc

MaCh3/samplePDF/samplePDFFDBase.cpp

Line 224 in 29484d5

MCSamples[sample].Oscillator->propagateLinear(nutype , *oscpars[7], *oscpars[8]);

MaCh3/samplePDF/samplePDFFDBase.cpp

Line 238 in 29484d5

GetProb(nutype, oscnutype, &oscpar[7], &oscpar[8], en, num, w);

tl:dr prob3++ can use baseline and densitiy as fit parameters, while currently cuda prob3 not
