cocytus update

Have implemented some of the data structures…not 100% it has everything needed, but will know as soon as the styx operations are implemented which is the next step. Will begin tomorrow with the fundamental, i.e. read/open/walk. This should give a good feeling for whether or not everything is working as it should and if the data structures are sufficient. Write will then be implemented once I am sure the basics are working properly. A semi-rough timeline would be to get the read/open/walk operations done by Wed-Thurs, then have write working by the end of the week.
