+/**
+ * @brief The NumericSpinBox class
+ * This class implements a spinbox for numeric SQLite types.
+ * This includes integers, as well as decimals.
+ * User is also allowed to type in any text value (unless "strict" property is set),
+ * but once he uses "step up" or "step down", the text value
+ * gets replaced with 0.
+ * If strict propery is set, also the allowEmpty property starts to matter.
+ * Otherwise allowEmpty is ignored.
