+Numeric array template class library. A numeric array, in addition to the usual array operations, is expected to have numeric data that can be added, subtracted, multiplied, etc.
+
+This numeric array class implements random number generation, threaded vector operations, threaded math and statistics for fast operations on the arrays.

+The primary object is the template class narray<T>
