  * SBjsiString, string class that is a subset of STL wstring
  *
  * The SBjsiString class stores a string in a grow-only buffer, a
  * functional subset of the STL wstring class. This header merely
  * exists to make it easy to eliminate the use of STL wstring which
  * does not exist on some Linux versions.
