The first thing to do when creating a new UCM3 model is to
create its directory tree. This, for the most part, will be
a single folder containing the following files:

modelname.UCM3	//manifest file
schemename.UCS3	//default color scheme
filename.bmp	//page image data

where modelname, schemename, and filename are placeholders
for the actual names of your model, default color scheme,
and the page data files.
