ive ported missing function 'drunk' and 'copier ' pattern to cm3 and  
updated documentation. note that the name 'copier' has been renamed  
'repeater' to better reflect what the pattern does. use 'make- 
repeater' to create a repeater pattern.  also fixed the documentation  
of rotation, which had incorrect ordering of rotation arguments.
