Detailed Description

This class inherits calculator QguListItem class. It includes all the parameters that are required for an object
created at the calculator (either an operation or float constant).

Those options are: the list of operands, the operator, working list name, virtual name (which is the operation name e.g. a + b),
the angle unit (if trigonometric operation), vector component (if vector decomposition operation), a pointer to the related tab
(created when an operation is added to the list view), a flag that signifies if the object is a constant float and a QdObject_var member for storing either the result of the operation or the constant float value. The main member functions are:
QcalcListVirtualItem::DoOperation() and QcalcListVirtualItem::DoMathOperation() that are recursively called from within the main loop of QcalcWindow::DoCalculation().
