Subject: Revamped transformation layout to remove need for the "01_files"
 level * "01_files" contained a single "source" transformation which listed
 the contents of the "00_content" level ** this was unnecessary as the base
 "list" transformation already lists the contents of all levels * added new
 "expression" mode to datasource meta tag processing in the task processing
 transformation ** this expression modes allows for the evaluation of
 arbitrary XPath statements *** e.g. a query to the results of "list.xsl" *
 modified base transformation datasource structures to include the level and
 meta tree * modified all existing content transformations to query the
 level-tree instead of the deprecated "source.xml" ** i.e. XPath statements **
 the main change is that directories are available as "directory" nodes
 instead of nodes named by the directory name * these changes where
 implemented to simplify the architecture and to increase flexibility
