Update README.md

hi, just a note that this conceptor project is not complete yet.

you may also be interested in BECCAj https://github.com/automenta/beccaj which is a Java implementation of http://openbecca.org.  That's more or less functional but still needs a lot of work, particularly making it 100% GPU accelerated.  It has some similarities to DeSTIN but 1) includes a reinforcement learning component and 2) can process N-dimensional data where DeSTIN assumes 2D.
