pattstorage interpolation wrapper

[img_assist|nid=166|title=interpolation wrapper|desc=download 7kb|link=url,http://www.tinpark.com/files/pattr_storage_interp_manager.zip|align=right|width=100|height=51] As it says, a wrapper for the pattrstorage object that permits managment of the interp functions of pattrstorage. Pattrstorage is queried for clients, these in turn generate three lists of clients (ints, float and list). These can each have their interp setting globally or individually changed. The reason I've divided up the clients crudely into data type is that I usually don't want to interp through ints but floats and lists I do. A better way to manage this would be to change the name of the objects when I make them - perhaps adding 'iON' to those that I would like to be part of the interpolation system and iOF to those I'd like to filter out but that would mean changing lots of objects in my patches and rewrites to presets that already exist. This code could also be adapted and used to create a similar wrapper for setting priority globally.
