Writer: add SetDoublePrecision to control number of significant digits
Writing a double to an OutputStream current prints at most 6 significant
digits (according to the C standard).
The function SetDoublePrecision(), added to the Writer classes
can be used to fluently set the precision, i.e. the number of
significant digits to use for writing the double:
Writer<...> writer(...);
d.Accept(writer.SetDoublePrecision(12));
