Function to return array of classes in stylesheet

[daveredfern]

Same as colours but returns an array of anything we want.

not sure what to call this function so open to ideas.

getCss('g-col-lg')

this would return an array of anything with g-col-lg in it.

I managed to do a regex that might help .([^\s,{]+) or .g-col-([^\s,{]+).

I can manually print them out once we have the array where ever we want them to appear.

@daveredfern has this been done now?

[daveredfern]

@Triickii yes, feel free to refactor it. If you look in utilities you can see what we're trying to achieve.
