Histograms are updated in 3 different views unde a separate tab menu.
The program now takes up to 10 different hosts specified at the
command line. The port needs not anymore to be spcified. If not
given on the command line after the -host <hostname> they are set to a default value
of 42001. Data from several hosts/ports are updated in a single display.
For the moment different modules might not be syncronized on the display
due to samll bug. Expect fix soon.
