Features

• traversable type class (util.data.traversable)
• cardinality type classes for types with a finite number of values and countably many values (util.data.finite, util.data.countable)
• category type class (util.category)
• tactics for proving efficiently inequalities between large literal numbers (util.data.norm_num)
• machinery for defining coinductive data types (util.data.coinductive)
• monad for expressing non-terminating computations (util.control.monad.non_terminating, now redundant with mathlib)
• Various lemmas complementary to the basic libraries
