/**
 * This class serves as a sort of (legacy) middleware for the main Farmhand
 * component. It defines stub methods with names that correspond to various
 * reducer functions. At the time of instantiation, it implements the methods
 * with the matching reducer function and binds it to the class instance.
 *
 * This is done in the interest of coding convenience and decentralization of
 * core game logic. It is implemented as a class so that the methods can be
 * statically analyzed by the TypeScript compiler.
 *
 * TODO: Replace this with a TypeScript interface
