-**  Name: umax
-**
-**  Description:    Implements a simple maximum function for unsigned numbers.
-**                  Implemented as a function rather than a macro to avoid
-**                  multiple evaluation of the calling parameters.
-**
-**  Parameters:     a, b     - Values to be compared
-**
-**  Global:         None
-**
-**  Returns:        larger of the input values.
-**
-**  Dependencies:   None.
