Hashing

Hashing is a trait whose instances each represent a strategy for hashing instances of a type.

Hashing's companion object defines a default hashing strategy for all objects - it calls their ## method.

Note: when using a custom Hashing, make sure to use it with the Equiv such that if any two objects are equal, then their hash codes must be equal.
