/**
 * @public
 * @description Convert a theme or a scopedTheme into a makeTheme.
 * @param {object} theme
 * @returns {function} makeTheme
 *
 * @example
 * const darkTheme = originalMakeTheme({
 *    '$body-bg': 'dark',
 *    '$body-color': 'white',
 *    '$btn-primary-bg': 'red',
 * });
 *
 * const darkMakeTheme = toMakeTheme(darkTheme);
 *
 * Now you can create a new theme starting from the personalized theme as default theme rather than the default original theme.
 * This allows others to build from your theme as a starting point and makes it a lot easier to share and make new themes.
 *
 * const anotherDarkTheme = darkMakeTheme({
 *     '$body-bg': '#121212'
 * });
 *
 * The method also takes care of scopedTheme so that you don't have to worry about a thing.
 *
 * const loginFormTheme = makeScopedTheme('loginForm', {
 *    '$body-bg': 'dark',
 *    '$body-color': 'white',
 *    '$btn-primary-bg': 'red',
 * })
 *
 * const loginFormMakeTheme = toMakeTheme(loginFormTheme);
 *
 * const anotherLoginFormTheme = loginFormMakeTheme({
 *     loginForm: {
 *        '$body-bg': '#121212'
 *     }
