* \brief A custom event that is designed to be fired when a layer count has been fully calculated.
\author Brendan Morley
\date March 2005
This custom QEvent is designed to be fired when the full item count of a layer has been calculated.
It was initially included in QGIS to help the QgsPostgresProvider provide the asynchronous
calculation of PostgreSQL layer counts.
Events are used instead of Qt signals/slots as events can be received asynchronously,
which makes for better mutlithreading behaviour and less opportunity for programmer mishap.
