+  * Created by chris on 5/22/16.
+  * CChainParams defines various tweakable parameters of a given instance of the
+  * Bitcoin system. There are three: the main network on which people trade goods
+  * and services, the public test network which gets reset from time to time and
+  * a regression test mode which is intended for private networks only. It has
+  * minimal difficulty to ensure that blocks can be found instantly.
+  * Mimics this C++ interface
