# Purpose: #
# Tests where the columns used within the partitioning function are altered. #
# This routine is only useful for the partition_<feature>_<engine> tests. .#
# Part 2: decreasing size of column
# #
#------------------------------------------------------------------------------#
# Original Author: mleich #
# Original Date: 2006-03-05 #
# Change Author: MattiasJ #
# Change Date: 2008-09-08 #
# Change: Splitted the test in two different parts (increasing/decreasing col) #
