Make all output be in a single file

Including color settings.

So the current file format is template based. Do you think we can change that? The major reason why this was important in Java TreeView was because people used Cluster 3.0 which spat out .cdt, .atr, and .gtr files.

I agree that this is very messy and maybe another way to store the data would be more practical and useful since clustering is now integrated.

Are the .atr, .gtr, and .cdt formats standardized? Could we create an additional merged format for when they save their work, but still handle these other formats? We'd just have to add code for determining format, reading, selecting output format, and writing. Might also be helpful to pop up a window after clustering to notify the user of the newly created file(s). --Just thinking out loud here - whatever is easiest.

Alternatively, we could output a session file that stores links to the various output files (perhaps all consolidated into their own directory along with a copy of the original input file...?).
