Retrieves the tags for a post formatted as a string.

More Information
This function generates a HTML string of the tags associated with the current post. The name of each tag will be linked to the relevant ‘tag’ page. You can tell the function to put a string before and after all the tags, and in between each tag. Differently from get_the_category_list, this tag must be used inside The Loop.
