/** \brief The ValueCache class provides a simple mechanism to recycle
unused value items.
This class serves as a factory for value items. It allows skipping
unnecessary and slow new/delete calls by storing unused value
objects in an internal buffer for later reuse. By eliminating new/delete
calls the parser is sped up approximately by factor 3-4.
