//! The storage system that was used in Crymap before version 2.0.
//!
//! V1 storage uses a complex and delicate "filesystem as a database" model,
//! described in more detail in each module.
//!
//! The code here is the entire storage layer from Crymap 1.x. In the binary
//! build, it is used in a read-only manner to migrate to the V2 model. Tests
//! do use the write support to generate scenarios to test the migration path.
