+ Load a YAML file containing an array, string, or hash, and return the data

+ The first parameter can be a file path or a URL.
+ The second parameter is the default value. It will be returned if the file

-For example:
+ For example:
- $myhash = loadyaml('/etc/puppet/data/myhash.yaml')
- $myhash = loadyaml('no-file.yaml', {'default' => 'value'})
- ENDHEREDOC
+ $myhash = loadyaml('/etc/puppet/data/myhash.yaml')

+ $myhash = loadyaml('https://username:password@example.local/my_hash.yaml')
+ $myhash = loadyaml('no-file.yaml', {'default' => 'value'})
