Subdirectory "scripts" created in RALICE.

This subdirectory contains some scripts to install the RALICE physics
analysis tools in standalone mode and also contains the files
evtwrite.cc and evtread.cc to run some tests.
The files evtwrite.log and evtread.log contain the output of successfully
run tests of these macros in order to check proper functioning.
As can be seen from the .log files, the tests run properly under
ROOT 3.00/06 using the old schema evolution.
