Store resources

Click here to store a few critical layout features for this data
(the width and height of the plotting window, the width of the
variable selection panel) and several logical variables set using
the options menu (showAxes, showPoints, etcetera).  Store that
information in a file named fname.resources (where fname is the
name of the current data) and it will be retrieved when you next
start XGobi using this same data.

This offers a simpler alternative to editing the XGobi resource
file using the "-name" option.

That file can be directly edited as well, to change other
resources on a data-specific basis, for example:

*XGobi.title:    XGobi: Hourly Residential Telephone Usage
*XGobi.iconName: XGobi: usage
*plotFont: -*-lucida-medium-r-normal-sans-20-*-*-*-*-*-*-*
*glyphType: 2
*glyphSize: 3
*brushColor0: white
*brushColor1: red
*brushColor2: green
