+# Mongoid::Document model for dc_piece documents.
+# 
+# DcPiece model is used for documents or pieces of web site which are common to site 
+# or perhaps to all sites in database. For example page footer is a good candidate 
+# to be saved in a dc_piece collection.
+# 
+# Documents in dc_pieces collection must have unique name assigned. Default DcPartRenderer
+# also looks into dc_pieces collection and collects all documents which belong to
+# current site (site_id field) and renders them according to div_id field value.
