PVector is float x, y, z container!

The way class PVector is defined in Trinket now makes it 100% useless!

I can't convert Processing's Python Mode sketches to Trinket b/c its fields are declared as datatype int:

• https://GitHub.com/trinketapp/processing.sk/blob/0.0.12/src/vector.js#L76-L82
• https://GitHub.com/trinketapp/processing.sk/blob/0.0.12/src/vector.js#L97-L102

Dunno whether this repo is active in order to apply this int_ to [ int_, float_ ] urgent fix.
