Generate a README.md file for projects utilising the 'templar' templating 
engine.

Usage:
    java -jar documentr-all.jar [OPTIONS}

All OPTIONS are optional

Where OPTIONS are one of 

 -h, --help              will print out a longer version of the usage message.
                         Note: If you use this parameter all other parameters 
                         are ignored

 ~ OR ~

 -d, --directory <arg>   The directory in which the 'documentr.json' file 
                         resides, default the current working directory
                         (i.e. '.')
 -e, --extension <arg>   The extension for the README file, default '.md'. Only
                         '.md' and '.adoc' are supported by the inbuilt 
                         templates, only other extension __MUST__ not use the 
                         'inbuilt' template type
 -v, --verbose <arg>     Output more verbose information

This will look for a documentr.json file in the directory, parse it, collate 
the associated resources and generate the documentation.
