Turn off indexing on Containers

[jcoyne]

I don't think we need it and it's less disruptive to add it later if we need it than to remove it. You can probably override update_index to be a nop

Do you not need it to do #find? If not, then :+1:

@terrellt I wouldn't think so, because we'd only want to find the container's parent, such as the Work or GenericFile. This class would have the /files or /members path that we could get to directly.

Does this require more discussion or development?
