@johlju, @PlagueHO,

Please can someone review when time permits?

Thanks for submitting @dan-hughes - awesome stuff! I'll get onto reviewing in the weekend.

[PlagueHO]

Sorry for not getting onto this yet - have had some other issues come up that need to deal with. Might have to be in the week :/

[PlagueHO]

Just need to get @kilasuit to sign off on comment and can merge.
