Generalised question dialog (questdlg)

Create and open a push button dialog box, which is a generalized version of a question dialog box (called by questdlg). User can enter any number of input options (buttons)for one to choose from, as opposed to questdlg, where only 2 or 3 options are supported. User can also set the buttons ordering (columns, rows). Dialog will attempt to set parameters to optimally present button text.
