Change file names and file extension names to reflect change to ROW/ COL label prefixes from old GENE/ ARRY

[Christopher Keil]

USE CASE: WHAT DO YOU WANT TO DO?

Saving tree files and K-means files (although K-means functionality is disabled, it is still in the code).

STEPS TO REPRODUCE AN ISSUE (OR TRIGGER A NEW FEATURE)

Cluster a file.

CURRENT BEHAVIOR

Tree files and K-means files will be saved using "g" and "a" in their names or extensions referring to the old GENE/ ARRY paradigm. In #214 this was changed to a more general ROW/ COL paradigm.

EXPECTED BEHAVIOR

• Instead of saving a col tree file under .atr --> save as .ctr (col tree) but still recognize .atr when loading.
• Instead of saving a col tree file under .gtr --> save as .rtr (row tree) but still recognize .gtr when loading.

Analog when saving k-means files (which aren't tree files but still distinguish by axis).

DEVELOPERS ONLY SECTION SUGGESTED CHANGE (Pseudocode optional)

Change file name/ extension strings in affected classes.

FILES AFFECTED (where the changes will be implemented) - developers only

HierCluster.java; ClusterController.java; ClusterFileGenerator.java; ModelLoader.java; maybe others...
