Class for performing a radix sort (fast comparisonless sort based on byte value) on various standard STL containers.
 This is a template class to allow it to deal with a variety of containers, and a variety of value types to sort on. In addition to providing the container and value type on construction, you also need to supply a functor object which will retrieve the value to compare on for each item in the list. For example, if you had an std::vector of byvalue instances of an object of class 'Bibble', and you wanted to sort on Bibble::getDoobrie(), you'd have to firstly create a functor like this:
struct BibbleSortFunctor
{
float operator()(const Bibble& val) const
{
return val.getDoobrie();
}
}
Then, you need to declare a RadixSort class which names the container type, the value type in the container, and the type of the value you want to sort by. You can then call the sort function. E.g. RadixSort<BibbleList, Bibble, float> radixSorter;
BibbleSortFunctor functor;
radixSorter.sort(myBibbleList, functor);
You should try to reuse RadixSort instances, since repeated allocation of the internal storage is then avoided.
 Note
 Radix sorting is often associated with just unsigned integer values. Our implementation can handle both unsigned and signed integers, as well as floats (which are often not supported by other radix sorters). doubles are not supported; you will need to implement your functor object to convert to float if you wish to use this sort routine.
