Visitor Pattern

[jakirkham]

In some cases, especially when copying between groups or searching for something in a group, it helps to have a visitor pattern by which one can visit all objects in a Zarr group and do something with them. h5py has the nice visit and visititems methods for Group. It would be really handy to have these same methods for Zarr Groups.

Ok, cool. I'll take a look.

Rough implementation of these in PR ( https://github.com/alimanfoo/zarr/pull/122 ).
