madcowswe 15:9c5aaeda36dc 38 * \brief Represents the expression for vectors at any node in the parse tree.
madcowswe 15:9c5aaeda36dc 39 *
madcowswe 15:9c5aaeda36dc 40 * Specifically, XprVector is the class that wraps the expression, and the
madcowswe 15:9c5aaeda36dc 41 * expression itself is represented by the template parameter E. The
madcowswe 15:9c5aaeda36dc 42 * class XprVector is known as an anonymizing expression wrapper because
madcowswe 15:9c5aaeda36dc 43 * it can hold any subexpression of arbitrary complexity, allowing
madcowswe 15:9c5aaeda36dc 44 * clients to work with any expression by holding on to it via the
madcowswe 15:9c5aaeda36dc 45 * wrapper, without having to know the name of the type object that
madcowswe 15:9c5aaeda36dc 46 * actually implements the expression.
madcowswe 15:9c5aaeda36dc 47 * \note leave the Ctors non-explicit to allow implicit type conversation.
