Description

Cloned from: 151: Enhancement: add "common" section to OR patterns\ https://github.com/ujhelyiz/EMF-IncQuery/issues/issue/151

Instead of:

   pattern inTheCircleOfFriends(S1:Student, Someone:Student) = {\
    find friendlyTo(S1,Someone);\
    S1!=Someone; // observer the evil duplicate code\
   } or {\
    find friendlyTo(S1,CommonFriend);\
    find inTheCircleOfFriends(CommonFriend,Someone);\
    S1!=Someone; // observe the evil duplicate code\
   }\

we could write something like this:

  pattern inTheCircleOfFriends(S1:Student, Someone:Student) = \
  {\
   S1!=Someone; // cleaner, dryer, safer feeling\
   } and {\
    {\
    find friendlyTo(S1,Someone);\
    } or \
    {\
    find friendlyTo(S1,CommonFriend);\
    find inTheCircleOfFriends(CommonFriend,Someone);\
    }\
  }\

The world would be a much better place.
