Enum reform::number::Number

pub enum Number {
    SmallInt(isize),
    BigInt(Integer),
    SmallRat(isize, isize),
    BigRat(Box<Rational>),
}

A number is either a small number consisting of machine sized integers or a big number, using GMP.

The mathematical operations on a number automatically upgrade and downgrade to bigint/smallint etc. TODO: hash should take into account that some bigints can be equal to smallint?
