OK, I've updated this to use as a reference. One thing we may want to take
from this PR is that toDataFrame and createDataFrame absolutely need to check
reserved words in column names. I've added the behavior in scala and in the
DataFrame Suite.
Perhaps I should just open a new PR with the reserved words checking?
I'll take a look at @davies PR when it shows up.
