[hoc-cvs] hoc/HOC_cbits Statistics.h, NONE, 1.1 Statistics.m, NONE, 1.1 NewClass.m, 1.3, 1.4

[Wolfgang T. <wth...@us...>]

Update of /cvsroot/hoc/hoc/HOC_cbits
In directory sc8-pr-cvs5.sourceforge.net:/tmp/cvs-serv6881/HOC_cbits

Modified Files:
	NewClass.m 
Added Files:
	Statistics.h Statistics.m 
Log Message:
a) Utilities cleanup:
	remove #* (send message and release result)
	add #. (get instance variable)
	add declareMarshalledObjectType
b) sending init messages to super is now supported
c) can now implement methods that return a retained object (like init)
