#Neo4jClient - It's Back!

###The Past

For those in the know - the main .NET client for Neo4j is Neo4jClient - it was developed by Tatham Oddie for the last few years and had reached a nice stable point. Tatham has had to take a more off-hand role - something called 'LIFE' has happened :) So, I (Charlotte - Hello!) have taken over the management of the Neo4jClient.

###The Now

The last Neo4jClient version prior to my taking over was 1.0.0.665 - which was stable and included a large amount of Cypher functionality, but crucially was missing Transaction support. As luck would have it the Transaction code (written by Arturo Sevilla) was sitting in a pull request.

	Wikipedia Trie

	This will generate a super simple (and it is super simple) Trie based on the Wikipedia entry on, well, Tries (see http://en.wikipedia.org/wiki/Trie), and _then_ look at how we can use that to do some simple things like intellisense and spelling guidance.
