// Utility functions for tightening up STL containers and strings.
// With C++11 STL containers and strings have a
// shrink_to_fit method. But since C++11 features
// are not supported equally well by all compilers we'll use a
// general trick that works well but just isn't as obvious to the
// casual reader of the code. This way, for now, everyone executes
// the smae code path. When C++11 support is more ubiquitous calls
// to this function can be replaced by calls to the shrink_to_fit
// method associated with the object.
