<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Taxonomy: Introduce the `is_term_publicly_viewable()` function.
This is the taxonomy term counterpart to the `is_post_publicly_viewable()` function. Although the logic for terms is more straight forward this serves the same purpose as introducing the corresponding function for posts -- to centralise and reduce the logic needed to validate a term and determine if it's publicly viewable.
