Add support for parameters in view / functions that return data

[GoogleCodeExporter]

Broader context: 
http://stackoverflow.com/questions/26217851/view-with-parameters-in-bigquery

Example of use:

CREATE data_view(TIMESTAMP date_param) AS
SELECT data.* FROM 
  data_table data
  JOIN EACH
  (  SELECT id, max(event_date) max_event_date FROM
       data_table
     WHERE 
        event_date <= $date_param
     GROUP BY id) max_data
   ON data.id = s.id AND data.event_date = s.max_event_date;

and use it as:
select * from data_view('2014-10-04 12:00:00');

It might be even more useful, if we can use it with table wildcard functions 
(e.g. TABLE_DATE_RANGE ).
