Please review treegrid pattern and example

Team,

 

As discussed in today's meeting, please review our current draft of the
treegrid pattern and example. There is a link to issue 91 at the start of
the pattern for pattern feedback. There is a link to issue 132 at the start
of the example for feedback on the example.

 

Our goal is to finish editorial clean up by mid week. It would help most if
you can review before end of day on Wednesday. I'll be fixing issues as
people report them.

 

Link to pattern:

The link to the example is in the pattern.

 

Thanks!

Matt
