PGS 1.1.1

Added

• voronoiCells() to PGS_Voronoi. Generates Voronoi diagrams from shapes or point sets, outputting the diagram as polygonal cells (rather than lines only, as before).
• Additional method signature for voronoiDiagram() that accepts a list of points (rather than PShapes only, as before).
• findContainedPoints() to PGS_ShapePredicates. Tests each point in a given point set whether it is contained in a shape, returning only those points that are contained.

Changed

• Constrained Voronoi diagrams are now constrained to envelope of input shape, rather than a arbitrarily large area.
• Refactored List<PVector> method arguments to Collection<PVector> where possible.

Fixed

• generateRandomPoints() no longer skips over small subsections of shapes when generating random points.
