[Tilesathome] Frustrated about oceantiles

There are many ready to use, but I think the problem is rather the 
"isClockwise(fragments of a poly)" ;-) the inversion bug that sometimes 
pops up with regard to close-areas seems to be a problem with the 
"contains" function which should actually be straightforward but does't 
quite seem to be.
