Simplify a fragment object by removing vertices bordering short edges while not encroaching on any of the outline. At present, this is done by finding concave vertices. It is safe to remove these, at the expense of increasing the area a bit.
simplifyFragment(P, min.frac.length = 0.001, plot = FALSE)
points to simplify
the minimum length as a fraction of the total length of the outline.
