+// This component extends the funtionality of QtControls 2.x Spinboxes to
+// - be able to contain fractional values
+// - hava a "prefix" and a "suffix". A validator is added that recognizes this pre-, suf-fix combo. When adding a custom
+//    validator the pre-, suf-fix should be added (e.g. new RegExp("^" + prefix + \regex\ + suffix + "$")
