A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).
