Macros to construct fixed-size hash types. Does not export any types.
Examples:
construct_hash!;
Add conversions between differently sized hashes:
construct_hash!;
construct_hash!;
impl_hash_conversions!;
Add conversions between a hash type and the equivalently sized unsigned int:
extern crate uint;
construct_hash!;
use U256;
impl_hash_uint_conversions!;
Build a serde serializable hash type:
construct_hash!;
