Minor breaking change: removed swapVariables() function

I just noticed we still had an old function lurking around called swapVariables(). Now that C++11 is mandatory, it’s vastly preferable to use std::swap so that it can use move operators where appropriate, so I’ve removed this old function. If you had been using it, it’s trivially easy to replace with std::swap!


Hey Jules, while you’re at it there’s a really old and dusty piece of code still lurking: BitArray

Ah yes, that’s overdue for the chop! Ta, will exterminate…
