+ * This is a translation of the C# Clipper library to Javascript.               *
+ * Int128 struct of C# is implemented using JSBN of Tom Wu.                     *
+ * Because Javascript lacks support for 64-bit integers, the space              *
+ * is a little more restricted than in C# version.                              *
+ *                                                                              *
+ * C# version has support for coordinate space:                                 *
+ * +-4611686018427387903 ( sqrt(2^127 -1)/2 )                                   *
+ * while Javascript version has support for space:                              *
+ * +-4503599627370495 ( sqrt(2^106 -1)/2 )                                      *

+ * Tom Wu's JSBN proved to be the fastest big integer library:                  *
