Defines a Tabular environment, which is (in effect) a tabular* environment that can split across pages. The major distinction is that \Tabular doesn't take an optional argument. It behaves much like \begin{tabular*}{\linewidth} with \Tabularleftskip and \Tabularrightskip used as the stretchable glue on either side. The package feels as if it were a predecessor of the current LaTeX longtable package.
