new package name (divergent fork)

- The API has diverged from gomdb and the C API in favor of more
  idiomatic Go.

- Improved documentation which improves usability and highlight
  differences from the C API.

- Zero-copy is the default behavior.

- Plans to provide a proper abstraction of thread safety in
  transactions.

- The package is experimental (hence the import's ".exp" suffix). So the
  API can change in to accomodate thread safety and usability concerns.
