/**
 * @namespace ARCH_GUI
 * @brief The ARCH_GUI namespace wraps the ImGui calls so that only a single
 * function is needed to load the menu. All menu functionality is handled
 * within, but the user has the choice to respond to Clicks, i.e. for sound and
 * is responsible for resetting it to false once handling it. The pause state
 * can also be accessed if further functionality such as key presses (Esc) want
 * to be used when interacting with the menu.
