[alexandria-devel] flatten depth param

[Robert Smith]

Hello:

I've created a patch for this. The only difference is that instead of
flattening to a particular depth, it flattens by a particular number
of levels. I thought this was more in the spirit of FLATTEN. If we
want to flatten to a particular depth, it is a trivial computation.

I've attached a patch for the function, as well as tests.

Cheers,

Robert Smith
