00038 
00039       There is no generic interface here since it would just be the 
00040       same as that from multi_inte. This class just provides the 
00041       generic Monte Carlo parameters and the random number 
00042       generator. The default type for the random number generator
00043       is a \ref gsl_rnga object.
