 Allocate an empty BufferBuilder. If you know approximately what size the Buffer will end up being and are trying to squeeze out more performance, you can set the initial size of the backing buffer.

+
+### appendString(string, [encoding])
+Append a string, encoded by utf8 by default. No trailing 0 is appended.
 
 ### appendUInt8(value)
