var mistigri = (function(){
/*
if (Promise === undefined)
{
    console.log("Making a fake Promise");
    var Promise = function Promise(execute) {
        this.then = execute;    // Mistigri always returns, even if it ran into problems
        this.catch = function(onrej) {
            return this;
        }
    }
}
