/**
* PropertyBinder helps synchronizing the values of 2 properties.
*
* Given 2 properties A and B of 2 QObjects, PropertyBinder::bind ensures
* that any change in value of property A happens to property B, and vice-versa.
*
* Warning: the properties' values are not made equal when binding. If you wish
* to make them equal, you ought to do so manually.
*
* There are bug reports pending in Qt's bug tracker requesting a similar
* functionality:
*
* http://bugreports.qt.nokia.com/browse/QTBUG-15104
* http://bugreports.qt.nokia.com/browse/QTBUG-5837
