A "file-backed" map, which inserts keys and values into a file in O(n) time, and gets the values in O(log-n) time using binary search and file seeking. For now, it only supports insertion and getting of (hashable) keys and values that implement the
FromStr traits (i.e., those which can be converted to string and parsed back from string).
See the module documentation for more information.
Note that this was an experiment, and so use it at your own risk!
