/**
 * Create a reducer builder, starting from its state.
 * It supports multiple actions (from typesafe-actions) with multiple reducers.
 * When the reducers are all set, just call build() to create the root reducer.
 *
 * It uses immer, which will produce an Immutable<TState> object as the result
 * of the reducer. The developer should edit the state in the reducer, instead
 * of creating a new one: immer will take care of creating a new object.
 *
 * The builder will provide type hints along all the build structure, lowering
 * the possibility of creating bugs.
 *
 * @param initialState the reducer's initial state
