Detailed Description
Create a numbered, unique, empty, writeable file, according to a format.
This class is derived from the std::ofstream class. Instead of a file name it accepts a c-style format that should work with a long integer. Opening a new file with that format is attempted, with the integer running from 0 to 999 (1000 unique files). The open method is overridden, for the rest of the methods this class follows the ofstream interface.
A suggestion for the format might be "myfile%03d.ext". This would produce files with names such as myfile000.ext, myfile001.ext, myfile002.ext etcetera.
