Merge branch 'issue/master/8797_puppetlabs-functions_merge'
Closes pull request #12
Reviewed-by: Jeff McCune
Verified all spec tests pass using rspec **/*_spec.rb
* issue/master/8797_puppetlabs-functions_merge: (164 commits)
* Moved kwalify to puppetlabs-kwalify project * Re-arranged tests in line with puppetlabs-stdlib
Prep for stdlib merge * Renamed load_yaml & load_json to parseyaml & parsejson * Renamed is_valid_* functions and remove the 'valid_'
Fix some ruby 1.9.2 issues.
(#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.
