V2.3.0

This release has a number of enhancements and fixes sine v2.2.9. There are now SAS Automatic Variables available for programmatic determination of code success or failure. The SAS process pid itself is available off the SASsession object for programmatic determination of whether the connection is valid. These help out in batch mode where, especially. There's a new dirlist() method, doc enhancements and a number of other user contributions as well. Also, the next version will have an overhauled rewrite of the proc generation code. So this release is the snapshot before taking all of those changes.
