* Implement the ewasm module and the EEI. * Add an ewasm standalone binary to test standalone files * use reflection to declare EEI module exports * check the module name when importing EEI functions * make eeiFuncs a function to avoid an init loop issue in call * Add a reference to the ewasm tests * wagon implementation of the Interpreter interface * update to wagon's PR #59 and uses the Process structure * Adapt to endianness change * All tests but 1 passing * CanRun only checks for the header * Add a "debug" module to support "printHex" in contracts Notes: * There are very little checks, e.g. of the call depths and so on.
