/**
* The pbf_builder is used to write PBF formatted messages into a buffer. It
* is based on the pbf_writer class and has all the same methods. The
* difference is that while the pbf_writer class takes an integer tag,
* this template class takes a tag of the template type T. The idea is that
* T will be an enumeration value and this helps reduce the possibility of
* programming errors.
*
* Almost all methods in this class can throw an std::bad_alloc exception if
* the std::string used as a buffer wants to resize.
*
* Read the tutorial to understand how this class is used.
