Taxonomy Children Context

Taxonomy Children Context provides a context relationship for ctools to return all children of a given term.

This can be used, for example, to generate this contetxt on an term panel and forward it to a view as argument. In this way the view avoids subselects and gains a better performance.

Example usage:

1. Build a view with a view pane display.
2. Add a contextual filter to term ids to that view pane. (Be sure that 'Allow multiple values' is checked for this contextual filter.)
3. Enter 'Argument input' of the view pane and select 'Input on pane config'.
4. Add the relationship and the view pane to a panel.
5. Find the context key 'Term ID of all term, separated by + or ,' (default is %term_children:tids). Add this context placeholder to the view pane settings in the panel.
6. Done.
