Merged requested to merge pe-add-header into master
This merge request adds the missing header
This bug has not been noticed since applications using the GJKEPACollideFunctor might include other headers that include
src/pe/utility/BodyCast.h. If these headers are included prior to
src/pe/fcd/GJKEPACollideFunctor.h, there will not be a compile-time error.
