The code change was surprisingly small.  I left the old css parsing in this change.  I'll remove it separately.

Not a huge fan of this name. I feel like it could easily be confused with the length after we've done the flex algorithm. How about mainAxisPreferredLengthForChild?

Don't necessarily need to do it in this patch, but these helper functions don't seem terribly useful to me.
