/**

 * This implements the Ethereum Kernel
3
 * The kernal handles the following
4
 * - Interprocess communications
5
 * - Intializing the VM and exposes ROM to it (codeHandler)
6
 * - Expose namespace which VM instance exists and Intializes the Environment (callHandler)
7
 * - Provides some built in contract (runTx, runBlock)
8
 * - Provides resource sharing and limiting via gas
9
 *
10
 *   All State should be stored in the Environment.
