/**
 * 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.
