bake b returns a block b' which has as predecessor block b. Optional parameter policy allows to pick the next baker in several ways. This function bundles together forge_header, sign_header and apply. These functions should be used instead of bake to craft unusual blocks for testing together with setters for properties of the headers. For examples see seed.ml or double_baking.ml
