Fill-Out Form Example #3
This is another fill-out form example, with multiple text entry
fields and checkboxes. 
 
Things you may want to note: 
-  By default, checkboxes are off.
-  When the query is packaged up, off checkboxes are ignored
     completely and on checkboxes are given the values specified by
     the VALUEattribute in eachINPUTtag.
-  Multiple checkboxes can have the same NAME, if
     desired.
-  Checkboxes are very similar in use and interpretation on the
     server side to text entry fields.
-  Checkboxes are "n of many": Any number of them can be on or off
     at any time.  (The alternative scheme, "one of many", in which
     only one out of a group of several toggle buttons can be on, is
     not yet supported by Mosaic.)
