Multi-threaded, coercion-free implementations of common row-wise operations

Fast row-oriented operations implemented in C++, all of which are multi-threaded by leveraging RcppParallel and RcppThread. Virtually no deep copies of input data are made, even of character data thanks to the 'string_ref' class from the C++ 'Boost' library. In contrast to other functions, the ones in this package support data frames with differently typed columns as input without coercing to a matrix, performing, if necessary, on-the-fly type promotion according to R rules (like transforming logicals to integers to allow summation).
