## Class Description

RooQuasiRandomGenerator()

     Perform one-time initialization of our static coefficient array if necessary
     and initialize our workspace.

~RooQuasiRandomGenerator()

void reset()

     Reset the workspace to its initial state.

Bool_t generate(UInt_t dimension, Double_t vector[])

     Generate the next number in the sequence for the specified dimension.
     The maximum dimension supported is 12.

void calculateCoefs(UInt_t dimension)

void calculateV(const int px[], int px_degree, int pb[], int * pb_degree, int v[], int maxv)

void polyMultiply(const int pa[], int pa_degree, const int pb[], int pb_degree, int pc[], int * pc_degree)
