//    Returns True or False, with ReturnArray passed by ref to give position

//    NOTE: ReturnArray[2] need to be declared prior to using this function.
//    Example 1:
//
//    double MySearchArray[10][5];
//    ArrayInitialize(MySearchArray,0);
//    MySearchArray [7][5] = 7;
//    double foo[2];  // this is the temp array that will store the search location
//    bool FoundIt = SearchSeconDim (foo,MySearchArray,7,MODE_ASCEND);  // searching for 7
//
//    This will set foo[0]==7 and foo[1]==5.  Also, FoundIt will be "true".

//    Example 2: 
//
//    double MySearchArray[10][5];
//    ArrayInitialize(MySearchArray,0);
//    MySearchArray [7][5] = 7;

//    bool FoundIt = SearchSeconDim (foo,MySearchArray,10,MODE_ASCEND);  // searching for 10
//
//    This will set foo[0]==-1 and foo[1]==-1 since the value isn't anywhere in the array's second dimension.
//    Also, FoundIt will be "false".
