%description
An implementation of the two-sample multivariate Kolmogorov-Smirnov test
described by Fasano and Franceschini (1987) <doi:10.1093/mnras/225.1.155>.
This test evaluates the null hypothesis that two i.i.d. random samples
were drawn from the same underlying probability distribution. The data can
be of any dimension, and can be of any type (continuous, discrete, or
mixed).
