-/* Adapted from MochiKit's example to use custom cubicweb attribute
-   and a stable sort (merge sort) instead of default's js array sort
-
-merge sort JS implementation was found here :
-http://en.literateprograms.org/Merge_sort_(JavaScript)
-
-
-On page load, the SortableManager:
-
-- Finds the table by its id (sortable_table).
-- Parses its thead for columns with a "mochi:format" attribute.
-- Parses the data out of the tbody based upon information given in the
- "cubicweb:sorvalue" attribute, and clones the tr elements for later re-use.
-- Clones the column header th elements for use as a template when drawing
- sort arrow columns.
-- Stores away a reference to the tbody, as it will be replaced on each sort.
-
-On sort request:
-
-- Sorts the data based on the given key and direction
-- Creates a new tbody from the rows in the new ordering
-- Replaces the column header th elements with clickable versions, adding an
- indicator (&uarr; or &darr;) to the most recently sorted column.
