2. Optional: Add filters for 'the_meta' to filter custom field data (see the end of the file for 
commented out samples you may wish to include).  *NEW*: Add per-meta filters by hooking 'the_meta_$field'

4. Give a post a custom field with a value.

5. Use the function freshout somewhere inside "the loop" and/or use the function c2c_get_recent_custom
outside "the loop"; use 'echo' to display the contents of the custom field; or use as an argument to 
another function


Function arguments:
    $field      : This is the name of the custom field you wish to display
    $before     : The text to display before all field value(s)
    $after      : The text to display after all field value(s)
    $none       : The text to display in place of the field value should no field value exists; if defined as ''
                and no field value exists, then nothing (including no $before and $after) gets displayed
    $between    : The text to display between multiple occurrences of the custom field; if defined as '', then
                only the first instance will be used
    $before_last: The text to display between the next-to-last and last items listed when multiple occurrences of
                the custom field; $between MUST be set to something other than '' for this to take effect
    
Additional arguments used by c2c_get_recent_custom():
   $limit       : The limit to the number of 
   $unique      : Boolean ('true' or 'false') to indicate if each custom field value in the results should be unique
   $order       : Indicates if the results should be sorted in chronological order ('ASC') (the earliest custom field value
                listed first), or reverse chronological order ('DESC') (the most recent custom field value listed first)
   $include_static : Boolean ('true' or 'false') to indicate if static posts (i.e. "pages) should be included when
                retrieving recent custom values; default is 'true'
   $show_pass_post : Boolean ('true' or 'false') to indicate if password protected posts should be included when 
                retrieving recent custom values; default is 'false'
                
Examples: (visit the plugin's homepage for more examples)

        <?php echo freshout('mymood'); ?>  // with this simple invocation, you can echo the value of any metadata field
        
        <?php echo freshout('mymood', 'Today's moods: ', '', ', '); ?>
        
        <?php echo c2c_get_recent_custom('mymood', 'Most recent mood: '); ?>
        
        <?php echo freshout('mymood', '(Current mood: ', ')', ''); ?>
        
        <?php echo freshout('mylisten', 'Listening to : ', '', 'No one at the moment.'); ?>
        
        <?php echo freshout('myread', 'I\'ve been reading ', ', if you must know.', 'nothing'); ?>
        
        <?php echo freshout('todays_link', '<a class="tlink" href="', '" >Today\'s Link</a>'); ?>
        
        <?php echo freshout('related_offsite_links', 
                   'Here\'s a list of offsite links related to this post:<ol><li><a href="',
                   '">Related</a></li></ol>',
                   '',
                   '">Related</a></li><li><a href="'); ?>
        
        <?php echo freshout('more_pictures',
                   'Pictures I\'ve taken today:<br /><div class="more_pictures"><img alt="[photo]" src="',
                   '" /></div>',
                   '',
                   '" /> : <img alt="[photo]" src="'); ?>

        Custom 'more...' link text, by replacing <?php the_content(); ?> in index.php with this:
        <?php the_content(freshout('more', '<span class="morelink">', '</span>', '(more...)')); ?>
