/**
* 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.
