v0.4.5:
	Initial testing;
	Added support for raw text files that represents a database;
	Fixed a bug that caused repetitive imports in ORM code output in some
	cases;

v0.4:
	UML Classes that are generalized from others are correctly the last
	classes written at generated code now, before this would case NameError;

	uml2orm_cg script has been updated, now it supports passing output files
	and passing what ORM code to generate aswell what SQL code to generate;

	Fixed a wrong check done in uml2orm/umlparser/xmi.py;

	Fixed wrong syntax for SQLite error messages;

v0.3:
	Fixed wrong class generation in case there were no attributes to 
	be initialized;

	Added support for XMI files (tested only with XMI files generated 
	by Umbrello);

	Operations defined as "pk" at UML design are not an argument at class
	initialization anymore (supposing they are auto-incremented). This may
	change in the future by adding something more explicit to the "pk"
	operation (like "auto-increment" or "ai" or something like that).
