PolyLine library

[Marcus]

Here's a small library that could be used for enemy movement in space shootemups (that's the only use I can think of), example included.

The truth is that I had made quite a nice shootemup that used the library. But when I was going to zip it I wanted to delete all built files (exe, n7a, n7b ...). Instead of deleting the exe file, I deleted the source code


Edit  I updated the zip with a new version of the library and some more examples of how it can be used in a shootemup.
