1.2.1.1 About Tcl Packages

Tcl package version numbers should be of the form:
```
     
             MAJOR_NUMBER.MINOR_NUMBER
```
These numbers should match the Ferret major and middle version numbers, respectively. So, for example, package Diagram 1.0 is intended to run on Ferret 1.0.x, while Diagram 1.1 should run on Ferret 1.1.x.
Since Ferret 0.x do not use formalized packages major_number should never contain 0.
