=head1 display_inputs

This *RECURSIVELY* displays inputs for a hash of html elements

Vars it needs: 
   classmetadata-- the hash of bunch of data:
   cgi -- inputs keyed on column names
   table -- table inputs are for
   columns -- list  in order want displayed inputs
   colnames -- hash of what to label inputs
   
errors		 -- hash of errors keyed on columns 


TODO -- make it recognize a general submit button for redisplaying
values on errors
