NativeNumericData and ReversedNumericData work together to provide a sneaky interface for automatically byte-swapping numbers, when necessary, to transparency support big-endian and little-endian architectures.
Both of these classes provide interfaces that accept a pointer to a numeric variable and the size of the number, and they can append that data to the end of a string, or memcpy it into another location.
The difference is that NativeNumericData simply passes everything through unchanged, while ReversedNumericData always byte-swaps everything. Otherwise, they have the same interface.
The transparent part comes from LittleEndian and BigEndian, which are typedeffed to be one of these or the other, according to the machine's architecture.

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.
