This function computes the Fresnel integral "FresnelI(z)" with argument "z" either real or complex, and where FresnelI(z) = FresnelC(z) + i*FresnelS(z).
USAGE: [FresnelI] = FresnelI(z, tol)
INPUT PARAMETERS:
z = complex argument of Fresnel integral (vector).
tol = absolute tolerance to evaluate the integral using "quadl"(scalar). default=1.0e-4
