 This abstract class gives a template for parsers of files representing

 Filename filter for APX files.

 Parses abstract argumentation frameworks in the logic programming
 format which is given by the following BNF
 (start symbol is S): 
  
 S      ::== "" | "arg" "(" ARGUMENT ")" "\n" S | "att" "(" ARGUMENT "," ARGUMENT ")" "\n" S 
 
 where "ARGUMENT" represents any string (without blanks) as a terminal symbol.

| CnfParser | 
 Parses abstract argumentation frameworks in the CNF/Dimacs Format used for the
 SAT solver competition (see also http://people.sc.fsu.edu/~jburkardt/data/cnf/cnf.html). 
 | 
| TgfParser | 
 Parses abstract argumentation frameworks given in the 
 trivial graph format which is given by the following BNF
 (start symbol is S): 
  
 S                      ::== ARGUMENTS "#" "\n" ATTACKS  
 ARGUMENTS      ::== "" | ARGUMENT "\n" ARGUMENTS 
 ATTACKS                ::== "" | ATTACK "\n" ATTACKS 
 ATTACK         ::== ARGUMENT ARGUMENT 
 
 where "ARGUMENT" represents any string (without blanks) as a terminal symbol.
