Description: Evaluation for density and distribution function of
        convolution of gamma distributions in R. Two related exact
        methods and one approximate method are implemented with
        efficient algorithm and C++ code. A quick guide for choosing
        correct method and usage of this package is given in package
        vignette. For the detail of methods used in this package, we
        refer the user to Mathai(1982)<doi:10.1007/BF02481056>,
