Enhanced uiputfile for IMAT toolbox.
filename = imat_putfile('initfile','dialogtitle')

IMAT_PUTFILE is a wrapper around UIPUTFILE that returns a fully qualified filename.
INITFILE is a string or cell array of strings that contains the file mask. If not supplied, '*.*' will be used.
DIALOGTITLE is a string containing the title for the file dialog.
FILENAME is the fully qualified filename selected. If the user cancels, FILENAME is -1.
FILTERINDEX is the index of the filter selected in the dialog box. Please see the help for UIPUTFILE for more details.
Error checking is minimal.
