/* 

The function validate expects 2 arguments . The first if frm => The form object which is to be validated 
The second is an array validate_data_arr : 
Each element of the array validate_data_arr is an array of the form 
'name_of_input_typ_in_form , 'name_of_js_library_function_to_be_called' , 'error_message_if_called_function-fails' , 'Optionally any munber of additional arguments expected the the function bein caled can be passed '' 

Eg.	var validate_data_arr=new Array(); 
validate_data_arr[validate_data_arr.length]= new Array("table[name]", "isEmpty","Please fill in your  user name"); 
validate_data_arr[validate_data_arr.length]= new Array("table[name]", "checkLength","Username should be between of 4 & 16 characters ",4,16); 
TBD : Can be Enhanced such that all the messages of one field can be clubbed together and shown.
