Input stream that gets its data from a large object.
Use this class exactly as you would any other istream to read data from a large object. All formatting and streaming operations of std::istream are supported. What you'll typically want to use, however, is the ilostream typedef (which defines a basic_ilostream for char). This is similar to how e.g. std::ifstream relates to std::basic_ifstream.
Currently only works for <char, std::char_traits<char> >.
