/*
Helper class that creates admin menu pages ( both top level menu pages and submenu pages )
Default Usage:

$args = array(
			'page_type' => 'menu_page',
			'page_title' => '',
			'menu_title' => '',
			'capability' => '',
			'menu_slug' => '',
			'icon_url' => '',
			'position' => '',
			'parent_slug' => ''
		);

'page_type'		(string) (required) The type of page you want to add. Possible values: 'menu_page', 'submenu_page'
'page_title' 	(string) (required) The text to be displayed in the title tags and header of
				the page when the menu is selected
'menu_title'	(string) (required) The on-screen name text for the menu
'capability'	(string) (required) The capability required for this menu to be displayed to
				the user.
'menu_slug'	    (string) (required) The slug name to refer to this menu by (should be unique
				for this menu).
'icon_url'	    (string) (optional for 'page_type' => 'menu_page') The url to the icon to be used for this menu.
				This parameter is optional. Icons should be fairly small, around 16 x 16 pixels
				for best results.
'position'	    (integer) (optional for 'page_type' => 'menu_page') The position in the menu order this menu
				should appear.
				By default, if this parameter is omitted, the menu will appear at the bottom
				of the menu structure. The higher the number, the lower its position in the menu.
				WARNING: if 2 menu items use the same position attribute, one of the items may be
				overwritten so that only one item displays!
'parent_slug' 	(string) (required for 'page_type' => 'submenu_page' ) The slug name for the parent menu
				(or the file name of a standard WordPress admin page) For examples see http://codex.wordpress.org/Function_Reference/add_submenu_page $parent_slug parameter
'priority'	    (int) (optional) How important your function is. Alter this to make your function
				be called before or after other functions. The default is 10, so (for example) setting it to 5 would make it run earlier and setting it to 12 would make it run later.

public $hookname ( for required for 'page_type' => 'menu_page' ) string used internally to
				 track menu page callbacks for outputting the page inside the global $menu array
				 ( for required for 'page_type' => 'submenu_page' ) The resulting page's hook_suffix,
				 or false if the user does not have the capability required.
