r = deflate(F,P); r = deflate(F,r); r = deflate(F,B), ...
The purpose of deflation is to restore quadratic convergence of Newton's method in a neighborhood of a singular isolated solution P. This is done by constructing an augmented polynomial system with a solution of strictly lower multiplicity projecting to P.
Apart from P, an instance of the type Point, one can pass various things as the second argument.
