 * Reducer that handles actions that modify the URL query parameters.
 * In this case, the actions replace a single query parameter at a time.

 * NOTE: This is *NOT* a Redux reducer. It does not map from (state, action) -> state.
 * Instead it "reduces" actions into URL query parameter state. NOT redux state.
