Function `fit( )` not used about divand.jl

[Alexander-Barth]

Indeed, the function fit is not used because the functions fithorzlen and fitvertlen generally work better. So far, I did not removed this function because it might break other users code and maybe someday a way is found to improve them.

If this function fit cause confusion, maybe we should remove it as mentioned here:

Thanks Alex,
it probably makes sense to keep it then.
It caused me a bit (not a lot) of confusion while trying to reply to a user email about how the fit was working, but now it's clear!

Would it help if we put them in a file called deprecated.jl ? (they would be still available but it would be clearer that they are not used)

Sure, that can be a clean way to do it. Or even if we write "deprecated" before the function definition in the source code can help when one has to dig into the code.
