/**
	@brief The ProjectDBModel class
	This model is intended to be use with the class projectDataBase
	and is designed to be displayed by the class QetGraphicsTableItem
	(but can be use by other view class since it inherit from QAbstractTableModel).
	This class should be sufficient to display the content of
	the project data base from a query set by the method
	void ProjectDBModel::setQuery(const QString &query).
	The indentifier method is used by widget editor to retrieve
	the good widget for edit the query.
	By default identifer returns the string 'unknow'.
	You should use setIdentfier method to set your custom identifier.
	At the time this sentence is written, there is two identifier :
	nomenclature
	summary
