//! IndraDB - a graph datastore.
//!
//! IndraDB is broken up into a library and an application. This is the library,
//! which you would use if you want to create new datastore implementations, or
//! plug into the low-level details of IndraDB. For most use cases, you can use
//! the application, which exposes an API and scripting layer.
