Dum* passing of Xsec in sample FD cosntructor

[KSkwarczynski]

We pass xsec here only to check if it's not null...

MaCh3/samplePDF/samplePDFFDBase.cpp

Line 15 in 9c24022

if(xsec_cov == NULL){std::cerr << "[ERROR:] You've passed me a NULL xsec covariance matrix... I need this to setup splines!" << std::endl; throw;}

Which is cofnusign as hell as we need still to SetXsecCov

MaCh3/samplePDF/samplePDFFDBase.cpp

Line 736 in 9c24022

void samplePDFFDBase::SetXsecCov(covarianceXsec *xsec){
