-/**
- * Framework class for strings that involve multiple values.
- *
- * Certain CSS properties such as border-width and margin allow multiple
- * lengths to be specified.  This class can take a vanilla border-width
- * definition and multiply it, usually into a max of four.
- *
- * @note Even though the CSS specification isn't clear about it, inherit
- *       can only be used alone: it will never manifest as part of a multi
- *       shorthand declaration.  Thus, this class does not allow inherit.
