updated PentTree

After the starfish design, I revisited the PentTree. The first thing I noticed was that it didn't make all the nice loops--connected rings of polygons. So I fixed that: check above the base, you should see eight pentagons that fit together making a loop.  Then I tweaked the pattern so it was a little better balanced. For the geeks, here's the code:

splitL{    right    scale 0.71925    right    ifsmall 0.002 { } {    sides 5    ifon none {       paint green       left       create splitL       right       create splitR    } { }    } }

splitR{    scale 0.71925    ifsmall 0.002 {} {    sides 5    ifon none {       paint olive       create splitR       left       create splitL    } { }   } }
