contained within a folder and all of its subfolders.

This is a RestClient implementor that points to Box's new upload domain,
https://upload.box.com/api.  All file writes are now routed to that
domain.

Each new 'subfolder' operation is performed with clone of the original

Update readme.markdown
Added async folder item limit/offset

This works a little differently than the sync GetFolder/GetItems: if
limit and offset are both left null, then the BoxManager just uses the
default values.  It does not get everything in the folder.  This is
because async operations tend more towards a 'paged' request style, but
I also wanted to introduce some backwards compatibility.
Extracted interfaces
