! \class SpreadsheetModel \brief Model for the access to a Spreadsheet This is a model in the sense of Qt4 model/view framework which is used to access a Spreadsheet object from any of Qt4s view classes, typically a QTableView. Its main purposes are translating Spreadsheet signals into QAbstractItemModel signals and translating calls to the QAbstractItemModel read/write API into calls in
