@croossin Need to do a little review, but it's at 100% documentation. A lot of it is redundant property name, or self explanatory property comments. Anything else you'd like done?

[xtopolis]

Ready for any final comments and whether or not I should add in build step or leave it to you.

[croossin]

Would be awesome to have as a build step @xtopolis - but how much of a lift is that?

[croossin]

@xtopolis Is it hard to get this in the build pipeline?

[xtopolis]

I'll be able to look into it by end of week/this weekend, sorry for the delay.

@croossin Merge away if ready
