* Toggles are persistent on a per browser session per course basis but can be made to persist longer by a small
* code change. Full installation instructions, code adaptions and credits are included in the 'Readme.md' file.

* I'm not completely happy with this solution as would rather embed in the colour
* picker code in the form, however I find this area rather fraut and I hear that
* Dan Poltawski (via MDL-42270) will be re-writing the forms lib so hopefully more
* developer friendly.
*
* Note: Colour names removed, but might consider putting them back in if asked, but
* at the moment that would require quite a few changes and coping with existing
* settings. Either convert the names to hex or allow them as valid values and
* fix the colour picker code and the CSS code in 'format.php' for the setting.
*
* Colour name to hex on: http://www.w3schools.com/cssref/css_colornames.asp.
