WordPress Settings API Class

Allows for easier creation of plugin settings pages by using an object orianted approach, with an API similar to the customizer.

An example

use Eighteen73\SettingsApi\SettingsApi;

$settings = new SettingsApi(

	'Plugin Settings',
	'manage_options',
	'plugin-name',
	100,

);

// Submenus: if top level menu is created.
