Description
This is the only thing that should be used in table.sort's "comp" function. It allows
a data description of how to sort tables to be written, instead of writing a custom sort
function over and over again, you just create a single table that defines the sort ordering
for a general table type.
Arguments:
entry1 (table) An entry in the table being sorted
entry2 (table) Another entry in the table being sorted
sortKey (non nil) A key in the entry arguments (tableX[sortKey]) to be used for sorting.
sortKeys (table) A table whose keys are all keys in entryX and whose values are all tables.
sortKeys options:
isNumeric - used if a string field should be converted to a number for comparison
isId64 - used for id64 fields which need special comparison functions
caseInsensitive - used for case insensitive string comparison
tiebreaker - the next key to be used if this one is tied
tieBreakerSortOrder - the sort order to be used with the tie breaker key
reverseTiebreakerSortOrder - a boolean which if set to true causes the tie breaker to use the opposite of the current sort order
sortOrder (number) Must be ZO_SORT_ORDER_UP or ZO_SORT_ORDER_DOWN
Return:
When sortOrder is ZO_SORT_ORDER_UP: entry1[sortKey] < entry2[sortKey]
When sortOrder is ZO_SORT_ORDER_DOWN: entry1[sortKey] > entry2[sortKey]
