I am removing this poster for two reasons. Firstly it is a small subset of the

paper with the same name and therefore does not describe the tape code in this
repository any further than the paper which is in this directory.  Secondly the
poster has been copied to the following official location for CASTOR
presentations (thanks Sebastien):
