//     Function: NativeNumericData::Constructor
//       Access: Public
//  Description: This constructor accepts a pointer to a data array
//               containing a packed numeric value, the offset within
//               the array at which the numeric value starts, and the
//               size of the numeric value.
//
//               It is essential that the array not be destructed or
//               modified as long as the NumericData object remains;
//               it may just store a pointer into that string's
//               internal buffer.

//               and sizeof are given.
