A small module to allow global config settings to be set for all services within the ShareLaTeX architecture.
You can specify a custom location for the settings file by setting the
SHARELATEX_CONFIG environment variable. E.g.
$ export SHARELATEX_CONFIG=/home/james/config/settings.development.coffee
Otherwise, the settings will be loaded from config/settings.NODE_ENV.coffee,
where NODE_ENV is another evnironment variable, or defaults to development.
The config directory is first looked for in the current directory, and then relative to the settings module directory.
