Detailed Description

Legendre-Tanh-Sinh (l,m,n)-eps Scheme.

Parameters

l	order of Gauss-Legendre integration within every fixed point iteration step
m	fixed point iteration steps, first step is a partial Jacobi-Newton, the rest are naive Richardson fixed point iterations
n	number of Chebyshev nodes to interpolate the exercise boundary
eps	final conversion of the exercise boundary into option prices is carried out by a tanh-sinh integration with accuracy eps
