Pig should not crash when it encounters an unknown function during interactive use
----------------------------------------------------------------------------------

                 Key: PIG-3
                 URL: https://issues.apache.org/jira/browse/PIG-3
             Project: Pig
          Issue Type: Bug
         Environment: hadoop 13.1, hacked pig
            Reporter: Ted Dunning


I get this.  The crash is unfortunate when all that happened is that I should have capitalized
count.

grunt> z = foreach y generate group, count(y);                                        
          
java.lang.RuntimeException: Function count not found.
