BigNumber class

Many operations in Ethereum operate on numbers which are outside the range of safe values to use in JavaScript.

A BigNumber is an object which safely allows mathematical operations on numbers of any magnitude.

Most operations which need to return a value will return a BigNumber and parameters which accept values will generally accept them.
