Contour Plots

Demo: http://bl.ocks.org/4241134

Computes a contour for a given grid function using the marching squares algorithm. Returns the contour polygon as an array of points. The grid function takes two arguments, x and y, and returns true if the specified point is inside the contour, and false for points outside the contour. The contour plugin can also take an optional starting point [x, y] on the grid.
