  (#3) Provide documentation for remaining functions.
  (#3) Apply missing documentation to more functions.
  Remove rand.
  Some improvements to values_at tests.
  (#1) provide some more detailed tests for a number of functions.
  Removed date stub since this functinality is available in strftime anyway.
  (#2) fix is_string finally so it also makes sure numbers return false.
  (#2) unstub is_valid_domain_name
  Added doc strings for first five functions
  Removed join_with_prefix.
  (#2) unstub is_valid_mac_address.
  Allow sort for strings.
  Count functionality overlaps with size - so removing it.
  Removed crontab functions instead of unstubbing them.
  Removed load_variables. load_yaml is sufficient to solve this problem on its own.
  Remove is_valid_netmask instead of unstubbing. Doesn't seem like a sensible function on its own.
  (#2) unstub is_numeric function.
