    ##
    # Tag that can be used to retrieve details about a single user. When using this
    # tag you can use the database table's column names as the keys, multiple keys
    # will result in multiple WHERE/AND clauses. In order to retrieve a user with
    # the Email address "me@awesome.com" you'd do the following:
    #
    #     {% user email="me@awesome.com" %}
    #         {{name}}
    #     {% enduser %}
    #
    # If you want to add an extra condition simply do the following:
    #
    #     {% user email="me@awesome.com" status="open" %}
    #         {{name}}
    #     {% enduser %}
    #
    # Note that this class is a Liquid block, not a tag. This means that you'll have to
    # specify the closing tag. The reason for this is that there are multiple columns
    # for the user table and using a tag in combination of a variable would result in
    # more code.
