Hello,

I would like to know if there is an easy way to change the MaximumExtrapolationColumn number in the odex() algorithm I’ve been looking for but I can’t find it.

If you give `MAXEXCOLUMN = 3` as a keyword argument to solve, it’ll throw a warning about it but it should still work.

I would highly recommended using the ones from OrdinaryDiffEq.jl though since they outperform the old ones in every test in the benchmarks.
