Package clock provides a small time abstraction so that time-stamped state (a sprite's creation time, and any future timed behavior) can be driven deterministically in tests.

Package id generates identifiers in the shapes spritzer uses.

Package server wires the sprite store behind a net/http router that speaks the Sprites REST surface over the /v1 path space.

Package sprite is a thread-safe, in-memory model of Sprites and their checkpoint/restore semantics.
