douglasgscofield/fastrank: Ranking Integer and Numeric Vectors with Low Overhead

Provides rank functions for integer and numeric with less overhead as base R `rank`, as alternatives to calling `.Internal(rank(...))` which is forbidden within packages. In avoiding the overhead, fastrank functions impose constraints on the user. The R wrapper `fastrank` does a bit of type checking and type-specific dispatch, while the C functions `fastrank_int` and `fastrank_num` are available for integer and numeric vectors, respectively, via `.Call`, and do no error checking.
