+Usage:
+
+brainfuck("++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>+.+++++++..+++.>++.<<+++++++++++++++.>.+++.------.--------.>+.>.");
+The default arguments make it use std::cout and an empty string as input.
+
+
+You can also use a string as input:
+brainfuck(",[.,]", "input");
+
+Or with a stream/container/iterator:
+brainfuck(",[.,]", std::input_iterator<char>(std::cin));
+
+
+You can specify the memory-units:
+brainfuck<int>("...");
+As long as the type has certain operators. The default output is comma-seperated, except for char.
+
+
+You can specify an output-iterator:
+brainfuck("...", "", std::back_inserter(my_vector));
+
