   * Mutators are the mechanism used to modify IR nodes. Since most nodes are
   * immutable or at least partially immutable changeing them can require creating
   * a new node. Base mutator at the moment is a dumb sample mutator that takes
   * any float of value 1.0 and converts it to 0.0; It is currently used as a
   * dummy example, however, we should make it a simple instantiation of all the
   * mutate functions on all node types so that people can inherit it, and only
   * specialize those nodes which they want to have a particular transformation.
