GNU R parallel pseudo random number generator 'sitmo' header files

 Provided within are two high quality and fast PPRNGs that may be
 used in an 'OpenMP' parallel environment. In addition, there is a generator
 for one dimensional low-discrepancy sequence. The objective of this library
 to consolidate the distribution of the 'sitmo' (C++98 & C++11), 'threefry' and
 'vandercorput' (C++11-only) engines on CRAN by enabling others to link to the
 header files inside of 'sitmo' instead of including a copy of each engine
 within their individual package. Lastly, the package contains example
 implementations using the 'sitmo' package and three accompanying vignette that
 provide additional information.
