# This is a method I use when working with slow ruby scripts that
# operate on huge datasets.
#
# It caches the return value of a block of extremely slow code
# in a file so that subsequent runs are fast.
#
# It's indispensable to me when doing edit-debug-edit-debug-edit
# cycles on giant datasets.

# loads ruby object from a cache file or (if cache file doesn't exist) runs
