Added a few simple routines in fft_parallel to read and write from/to a distributed array.
...
not for efficiency but to make examples easier.
added test0 that uses fwfft and invfft, slight change to test
added a few directories (not yet used) to better organize the library

Added an experimental version with double-buffering for the pack_group_sticks. The target is to overlap the communication therein with the computation of the FFTs. It can be activated adding -D__DOUBLE_BUFFER

- more library self testing code
...
- there is another dependency from QE... the clocks! we need to rethink timing for the libraris,
meanwhile, a dirty fix has been included in the self testing program
