Testprograms for the Chebychev solver for the helmholtz equation.

To build: make a 
          make b2

Executables: a,b2
Parameters: N,M gives the number of gridpoints in each direction. 
            Any N or M  > 6 can be used.

Performance: Best performance by using 2^i-1 for N & M for any i in I >3 
             This is due to the fft-transform used.
