Module documentation for 0.1.2

Extensible type-safe unions for Haskell with prisms using modern GHC features. Dual to vinyl records. Unions are also known as corecords or polymorphic variants. Neither requires a Typeable constraint nor uses unsafe coercions at the cost of linear time access (negligible in practice).
