This is a minor release adding a new integration domain (non-negative real numbers) and minor bug fixes (including spelling errors).
New integration domain P = (0,\infty)^n with associated generic classes and two integration functions (log-normal and log-t densities).
New integration test function BFN4 for the unit hypercube.
Rewrites exactIntegral method in standardSimplex_exp_sum.R to avoid using the gsl package.
