    # lookup filter
    #
    # A liquid filter that takes an author slug as "input" and extracts from the
    # data set in the first arg the value of the key in the second arg for "input"
    #
    # Example:
    # if we have a variable `author` set to "boone" the following syntax:
    # ```
    # {{author | lookup:"authors, full_name"}}
    # ```
    # Will look for an entry in the authors data file named "boone" and exact
    # the value assocated with "full_name."
    #
    # Returns a string containing the requested value

    # A liquid filter that takes an author name as "input" and returns a link to an author's

    # {{ author | team_link }}
    # ```
    #
    # Returns an <a> tag linked to boone's author page
