Title: Separater generator

This class is useful to insert separators in for or while loops.
In that situation, we sometimes meet the request in which
only the first time doesn't add the seprator like the following.

string s; // ex. "A, B, x, y";
while ()
{
insertCommaExceptFirstTime(s);
s += value[i];
}
