Note about complex numbers in WAT.
     ----------------------------------

   The complex numbers in WAT were used only in procedure WaveDataTD::DFT(). 
Now this procedure is abandoned in favour of WaveDataTD::FFT() procedure with
the same functionality, but performing much faster.

   Anyway the complex numbers are still retained in WAT bearing in mind
their future use. It should be noted that class of complex numbers
still has not standard implementation. We choose g++ class implementation.
This is good for standalone code generation. For this to work for shared
libraries generation (for use with ROOT) I copied the file complex.h from 
the directory tree of g++ and placed it in the WAT source directory. This
file will have the preference over other complex class descriptions.
