// SimNetParams defines the network parameters for the simulation test network.
// This network is similar to the normal test network except it is intended for
// private use within a group of individuals doing simulation testing and full
// integration tests between different applications such as wallets, voting
// service providers, mining pools, block explorers, and other services that
// build on Bitum.
//
// The functionality is intended to differ in that the only nodes which are
// specifically specified are used to create the network rather than following
// normal discovery rules.  This is important as otherwise it would just turn
// into another public testnet.
