Method Inst_MoveTargetForward5

avida-core/source/cpu/cHardwareCPU.cc:8949–8993

This command should move the organism to the neighbor cell that is a target. If more than one target exists, it moves towards the last-seen one. If no target exists, the organism moves forward in its original facing. This version ignores the neighbors beind the organism, i.e. the cells directly behind and behind and to the left and right.
