# Test for the splattotable task
# </etymology>
#
# <synopsis>
# Test the splattotable task and the sl.splattotable() method upon which it is built.
# </synopsis> 
#
# <example>
#
# This test runs as part of the CASA python unit test suite and can be run from
# the command line via eg
# 
# `echo $CASAPATH/bin/casapy | sed -e 's$ $/$'` --nologger --log2term -c `echo $CASAPATH | awk '{print $1}'`/code/xmlcasa/scripts/regressions/admin/runUnitTest.py test_splattotable[test1,test2,...]
#
# </example>
#
# <motivation>
# To provide a test standard for the splattotable task to ensure
# coding changes do not break the associated bits 
# </motivation>
