btreedb is a simple ORM-like wrapper for Pycopy's
btree
module.
Note that it's recommended to use the btree module directly, but if
you want to build an abstraction on top of it, btreedb may show an
example of doing that.
For more information, see https://github.com/pfalcon/picoweb .
An example application where this module is used is https://github.com/pfalcon/notes-pico .
