Documentation error for lamellar_stack_paracrystal model

[jfmoulin]

Describe the bug Equation 4 of the doc page for the paracrystal lamellar model is incorrect:

S_N(q) = \frac{a_N}{N}[1 + w^2 - 2 w \cos(q \langle D \rangle)]^2

should instead read:

S_N(q) = \frac{a_N}{N [1 + w^2 - 2 w \cos(q \langle D \rangle)]^2}

The c code computing the model correctly implements the second form of the equation.
