Detailed Description

Simple counter class.

CTBcounter is not much more than a double variable wrapped into a class. The key difference to a double variable is that the counter is initialized with zero at construction time. This makes CTBcounter especially useful in a context like:

    CTBmap<CTBstring,CTBcounter>  word_count;
    CTBstring                     word;
    ...
    word_count[word]++;
    ...

where only the behavior of the default constructor can guarantee that the counter is initially zeroed.
