**vutil: Tcl Variable Utilities**
I created a package that handles TclOO garbage collection, introduces the concept of object variables, and provides a type system framework.

The following code demonstrates some of the features of the package:
======
package require tin
tin import vutil
# Factory procedure (creates objects)
proc foo {who} {
    new string message {hello }; # initialize object
    append $message $who; # modify directly with Tcl commands
    return [$message --> &]; # copy to shared object and return
}
[foo {world}] --> bar; # create from procedure
$bar = [string toupper [$bar]]; # value assignment
$bar print; # additional object methods
======

The package is a [Tin] package, so if you have Tin installed, the "tin import vutil" command will install the package on the fly, as well as load the package and import the commands.
