Live chart of CNTK Error Rate

CNTK is Microsoft's deep learning toolkit. This snippets allows one to view the live error rate on a chart. It relies on FSharp.Charting and FSharp.Control.Reactive and a couple of other F# snippets the links for which are referenced in the code. Use 'track' function to start viewing live charts.
