Rename all the "newClass" pseudo-constructors to "create".

Rename all the "newClass" pseudo-constructors to "create".

Since these are static methods, you need to type the class name anyway,
so there is no need to type it again after "new". Plain "new" would have
been ideal, but unfortunately it is a keyword.
For consistency, the Caps constructors have been renamed too, although
they did not follow the "newClass" pattern.
