/*
   Macro to test functionality of the AnliAnalysisTaskFiltered.
   To be used within UnitTest suit
   $ALICE_ROOT/test/testAliAnalysisTaskFiltered/AliAnalysisTaskFilteredTest.sh
   To test:
   1.) CPU/Memory/Data volume
   2.) Relative fracion of the information in exported trees
   3.) Compression for points
