  is not backwards compatible.
* Added HierarchyLookupTransform.
* Added DefaultTransform which will return a specified value if the initial value is blank.
* Added row-level processing.
* Added HierarchyExploderProcessor which takes a single hierarchy row and explodes it to multiple rows
  as used in a hierarchy bridge.
* Added ApacheCombinedLogParser which parses Apache Combined Log format, including parsing of the 
  user agent string and the URI, returning a Hash.
* Fixed bug in SAX parser so that attributes are now set when the start_element event is received.
* Added an HttpTools module which provides some parsing methods (for user agent and URI).
* Database source now uses its own class for establishing an ActiveRecord connection.
* Log files are now timestamped.
* Source files are now archived automatically during the extraction process
* Added a :condition option to the destination configuration Hash that accepts a Proc with a single
  argument passed to it (the row).
* Added an :append_rows option to the destination configuration Hash that accepts either a Hash (to
  append a single row) or an Array of Hashes (to append multiple rows).
* Only print the read and written row counts if there is at least one source and one destination
  respectively.
* Added a depends_on directive that accepts a list of arguments of either strings or symbols. Each
  symbol is converted to a string and .ctl is appended; strings are passed through directly. The
  dependencies are executed in the order they are specified.
* The default field separator in the bulk loader is now a comma (was a tab).
