String.Chars protocol

The String.Chars protocol is responsible for converting a structure to a Binary (only if applicable). The only function required to be implemented is to_string which does the conversion.

The to_string function automatically imported by Kernel invokes this protocol. String interpolation also invokes to_string in its arguments. For example, "foo#{bar}" is the same as "foo" <> to_string(bar).
