playing with the installation scripts to actually remove the installed binarycpython version and then install a new one

merged the HPC branch. going over all the pylint errors, this will take some time. need to change alot of things

clean up open() functions to use self.auto() which does compression for us based on the file extension

update _const_dt to include a wrapper just before it's cached, allowing output to the screen for debugging

other minor fixes

more attempts to clean up the code to work better on NFS : seems ok now, but expect more "bug" fixes to come (and more cleanup as the code is a bit hacky)

few other cleanups

add automatic cacheing of various functions, and a cache_test() routine to test the runtimes with and without caching

attempt to fix (finally?) the joingingfile logic
