# A sorter is used for allowing the user to sort the queried data
# according to a certain logic. All sorters declare in plugins/views/*.py
# are available for the user.
#
# Each sorter is a dictionary with the following keys:
#
# "title":    Name of the sorter to be displayed in view editor
# "columns":  Livestatus-columns needed be the sort algorithm
# "cmp":      Comparison function
#
# The function cmp does the actual sorting. During sorting it
# will be called with two data rows as arguments and must
# return -1, 0 or 1:
#
# -1: The first row is smaller than the second (should be output first)
#  0: Both rows are equivalent
#  1: The first row is greater than the second.
#
# The rows are dictionaries from column names to values. Each row
# represents one item in the Livestatus table, for example one host,
# one service, etc.
