Added the analytic implied volatility approximation of J. Choi, K Kim
and M. Kwak (2009), “Numerical Approximation of the Implied Volatility
Under Arithmetic Brownian Motion”, Applied Math. Finance, 16(3), pp.
261-268.

Given the premium of an option, it provides an analytic approximation of
implied volatility of the Bachelier formula. In interest rate the
volatility is referred to as bpvol.
Removed extraneous parameters.
Added new example to tests.
Added newly generated file to distribution.
Removed unreachable return statement.

Add UnaryFunction support to the SWIG Java/Scala modules in order to
enable integrals and root finding.
Also add integration methods based on Gaussian quadratures.
