Detailed Description

Class allowing different systems for mapping and rendering icons.

Possible icon styles are:

1. standard - image tags are generated which point to pix icons stored in a plugin pix folder.
2. fontawesome - font awesome markup is generated with the name of the icon mapped from the moodle icon name.
3. inline - inline tags are used for svg and png so no separate page requests are made (at the expense of page size).
