plyrmr.options always returns a list
needs a generic def
don't use unveiled
needs two methods for output
only use unified options system
convert tests to quickcheck, add dcast
a few methods and functions fell through the NAMESPACE cracks
normalize col order (name over position)
function to mark tests that are not spark-ready
formatting
list of backends and function to test a block on all three
don't take only the first var
transform is gone, only in ext pack
running tests on backends, skipping spark when necessary
convert tests to quickcheck, add dcast
normalize col order (name over position)
don't take only the first var
transform is gone, only in ext pack
preserve colnames
this was cherry picked a little too fast from spark
