//     recursively generates a Cantor distribution.
//   Inputs :
//	x 	signal of size n, (initialized by x = zeros(1,n))
//	n1 	left border (initialized by 1)
//  	n2	right border (initialized by n)
//	a1,a2	first and second cutting position (for example 1/3 and 2/3)
//  	b1,b2	weights to apply on [n1,a1] and [a2,n2]
