svn commit: r12904 - trunk/src/model/src/org/argouml/model/Model.java

Author: mvw
Date: 2007-06-24 05:54:35-0700
New Revision: 12904

Modified:
   trunk/src/model/src/org/argouml/model/Model.java

Log:
Shorten the Main.main() method. 

There is no reason the org.argouml.application package should know about a ModelImplementation; 

now it is just a string we hand to the org.argouml.model subsystem.
