-/**
- * A simple utility for shortening identifiers in a stable way. Generates
- * short substitution strings deterministically, using a compact
- * (1 to 6 characters in length) repesentation of a 32-bit hash of the key.
- * The string is suitable to be used as a JavaScript or CSS identifier.
- * Collisions are possible but unlikely, depending on the underlying hash algorithm used.
- *
- * This substitution scheme uses case-sensitive names for maximum
- * compression. Digits are also allowed in all but the first character of a
- * class name. There are a few characters allowed by the CSS grammar that we
- * choose not to use (e.g. the underscore and hyphen), to keep names simple.
- *
- * Xid should maintain as minimal dependencies as possible to ease its
- * integration with other tools, such as server side HTML generators.
