+/**
+ * \brief Scalar Widget - A labelled text box, with spin buttons and optional
+ *        icon or suffix, for entering arbitrary number values. It adds an extra
+ *       number called "startseed", that is not UI edittable, but should be put in SVG.
+ *      This does NOT generate a random number, but provides merely the saving of 
+ *      the startseed value.
+ *
