====== Module implementation: adding themeability ======

Previously released versions of the module merged walking the taxonomy tree with rendering for most situations, leaving little room for themeability.
 
===== taxonomy_context_show_children =====

This has been split in three parts:

  * Data is obtained in the new _taxonomy_context_build_tree($context->tid, $base)
  * Rendering is performed in the new theme_taxonomy_context_children_list($tid, $base = FALSE)
  * A deprecation warning is inserted in the obsolete taxonomy_context_show_children

===== taxonomy_context_show_nodes =====

This has been split in three parts:

  * Data is obtained in taxonomy_context_nodes($tid)
  * Rendering is performed in the new theme_taxonomy_context_nodes()
  * A deprecation warning is inserted in the obsolete taxonomy_context_show_nodes
