[Additions]
- Improved row creation so that it can create more then one space
(tested up to three). Anymore then three spaces looks bad for there
will be an option to remove nodes.
- Fixed bug with caution sign. Would keep on repeating the process as
well as sometimes call different orientations.
- Added a 6 node row and an 8 row node. Script should now work for any
node type, just need to make the row prefab first.
- Idea is to make game use 6 nodes and a caution difficulty option will
create eight nodes. Will have to do some work to make this happen, but
the code can create holes for 6 or 8 nodes rows.
