re-enabled clutter_sensitivity in the main bash script
1. now reads the list of stations from stations.txt; 1. the date has been changed to a date that is part of the testdata, otherwise the resulting image is empty.
maxz could be initialized to 1.0e10 and then later on it is converted to a LONG data type. This caused a type conversion error because 1e10 doesnt fit in LONG=32-bit signed. So I changed the initial value of maxz to 1e9 (without really checking what it does :p )
1. commented the call to PSTRACKER, since that function does not exist on my system; 1. added the visualization output directory to the psfile, such that the postscript file ends up in the right directory.
