changed target_accuracy in boost_main
added the ability to pass a dimension permutation to highlevel_pyramid
added code to bias the top level of the pyramid. biasing all levels depends on refining RandDistr
semicolon
adding more pyramid matfiles
save the pool with a name also based on the permutation used
removed the set_perm() method and associated tests. added permutation as a param when creating the pool of pyramids.
results of some condor runs, may not be useful going forward
adding 4-level pool, size 300
results of an old experiment. likely not useful any longer
ramanan versions of boost. todo: merge these to avoid duplicated code
add a version of highlevel pyramid that takes a pool as a parameter
