    //     ##################################################################################
    //     The first function here GenericLMM_MCPricer(), contains a series of
    //     function calls leading upto the main function call, the second function
    //     within this file ( GenericLMM_MCPricerPart() ).
    //     which contains the answer that we are looking for.

    //     The first function here is simply an example of how to construct the parameters 
    //     in order acquire either a string Key (that is to be passed to other functions) 
    //     or a computed result.
