Detailed Description

Calculate the AsymmetricEnge function (e.g. for multipole end fields).

AsymmetricEnge function is given by
\(T(x) = (tanh( (x+x0)/\lambda )-tanh( (x-x0)/\lambda ))/2\)
The derivatives of tanh(x) are given by
\(d^p tanh(x)/dx^p = \sum_q I_{pq} tanh^{q}(x)\)
where \(I_{pq}\) are calculated using some recursion relation. Using these expressions, one can calculate a recursion relation for higher order derivatives and hence calculate analytical derivatives at arbitrary order.
