Contract Implementation

The main contract is already defined here and just implements the ERC20 interface.

The contract implementation overrides the decimal() method of the ERC20 interface to allow a 6 decimal representation. This because the generated bindings only accept a big.Int which can represent values up to 64-bit signed integrers (9*10^18 aprox.). This would mean that only a totalSupply of 9 full tokens would be possible with 18 decimals. Since this is just a learning tool, the default decimals have been lowered to 6, allowing more possibilities.
