HL7 file viewer/editor, in tree-view format. Version 2.0 is out now (consider it a beta release for now) with the first release of my new macro feature - you can now automate some of your testing tasks in JavaScript (details in Discussion forum). The purpose of this project is to assist in testing and bug-tracing HL7 communications.
Red/Black Tree implementation. Port of the sourceforge libredblack library to C#. The package also consists of mutlitree (tree with non-unique key) and tree with quick direct access to items by the index.
