[Scopeapp-cvs]scopeapp/src ScopeController.h,1.9,1.10 ScopeController.m,1.14,1.15 ScopeAppDelegate.m,1.19,1.20

[<sco...@li...>]

Update of /cvsroot/scopeapp/scopeapp/src
In directory sc8-pr-cvs1:/tmp/cvs-serv18754/src

Modified Files:
	ScopeController.h ScopeController.m ScopeAppDelegate.m 
Log Message:
Make ScopeController take a class of input sampler to create, not an actual
input sampler object; this allows the input sampler's error messages to be
displayed in a more sensible manner, using a sheet on the scope window.
