* - if the field has options, the default has to be the

* - if the field is a text field, the default **has** to be
* an empty string as otherwise the user can't save
* an empty value/delete the meta value
* - if the field is a checkbox, the only valid values
* are 'on' or 'off'
* (semi-required) 'options' => (array) options for used with (multi-)select and radio
* fields, required if that's the field type
* key = (string) value which will be saved to db
* value = (string) text label for the option
* (optional) 'autocomplete' => (bool) whether auto complete is on for text fields,
* defaults to true
* (optional) 'class' => (string) classname(s) to add to the actual <input> tag
* (optional) 'description' => (string) description to show underneath the field
* (optional) 'expl' => (string) label for a checkbox
* (optional) 'help' => (string) help text to show on mouse over ? image
* (optional) 'rows' => (int) number of rows for a textarea, defaults to 3
*
* (optional) 'placeholder' => (string) currently not used in this class
*
* {@internal
* - Titles, help texts, description text and option labels are added via a translate_meta_boxes() method
* in the relevant child classes (WPSEO_Metabox and WPSEO_Social_admin) as they are only needed there.
* - Beware: even though the meta keys are divided into subsets, they still have to be uniquely named!}}
