Debug possibilities for smart properties.

In smart properties, when some error occured, is quite hard to assign address of excpetion or smart property object and it's real variable name in debugger.

Variable naming

Smart help is naming properies. It works very simple, everywhere, when out constructs a smart property, add as parameter any name. On opposite side, then you want retrieve a name you my call AMVariableNames::getVariableName(). Of cource, this functionality can be switched off in release. AMVariableNames will store and looking into any string at runtime. Default state is disabled. State is typically switched on on application init procedure. Let's say, that this works for all variables, not only for smart properties.

Method to_string

Every propery has a function to_string. AS expected, this function return std::string with dump of property. However, since base class AMPropertyBase is not virtual, calling to_string via this base pointer reutuns very brief informations.

Tracing

There are small amout of types of errors, that may ocuured during computation of smart properties. Computation can throws exceptions AMPropertyNestingException in case of computing depth is too big, AMPropertyLoopException, when copunting loop is detected or AMPropertyDeletedException, when you try to use deleted smart property (smart property assigned to AMProperyPool::defaultPool()). There is a chain of properties involve in excpetion. Entering smart property, which was computation initiated, last property in chain, which exception caused, and whole chain are available by calling simple methods of every exception.
