The amount of css rules required for this plugin is quite high. To accomodate the
moodle plugin practice of plugin specific css selectors, this makes the css rules
quite hard to maintain.

Unfortunately, moodle does not extend the sass/scss compiler support to plugins
that are not a theme.

To alleviate this, this plugin extends moodle's Gruntfile.js scripts
to compile 'scss/styles.scss' into 'css/devstyles.css' (and 'styles.css')

'css/devstyles.css' is used instead of styles.css in order to avoid having to clear the theme
cache every time a style rule is changed during development.

Once I devise a method to use styles.css in production environtments and css/devstyles.css
production environments, the compiler will compile it into both css/devstyles.css
and styles.css

The grunt command to compile is 'grunt scssplugin'
