drush / Crosstab for Ruby

Created March 8, 2010 21:15

A helper to convert model arrays into crosstab reports

	# Crosstab module for ruby. This class allows you to iterate through an
	# array of models (rows) and refactor the data to a crosstab format.
	# This takes one of the columns and makes it your row-key, another column
	# and makes it column-keys, then sums all cell values where these two
	# keys interesect.
	#
	# Currently only a single column can be used for row-keys and column-keys
	# but this may be expanded in the future with the addition of 'row grouping'
