/**
* DDRange is the functional equivalent of a 64 bit NSRange.
* The HTTP Server is designed to support very large files.
* On 32 bit architectures (ppc, i386) NSRange uses unsigned 32 bit integers.
* This only supports a range of up to 4 gigabytes.
* By defining our own variant, we can support a range up to 16 exabytes.
*
* All effort is given such that DDRange functions EXACTLY the same as NSRange.
