NmAdder creates chip definitions in AstroChip, which add n numbers
with m bits. The usage of this JAVA program is "java NmAdder test.txt m n"
to create the AstroChip definition in test.txt. m and n must be
positive integer numbers. The adder logic is based on adding all
bits of one position and carrying them. The constants "CONSTANT cixj v;"
at the beginning of "MODULE main" are filled with random numbers at
the time of generation. These are the bits of the numbers to be added.
