//! These contain the server "cores". These are able to startup the server
//! (bootstrap) to a running state and then execute tasks. This is where modules
//! are logically ordered based on their depenedncies for execution. Some of these
//! are task-only i.e. reindexing, and some of these launch the server into a
//! fully operational state (https, ldap, etc).
//!
//! Generally, this is the "entry point" where the server begins to run, and
//! the entry point for all client traffic which is then directed to the
//! various `actors`.
