Yep - you can call:

   mystate -> apply () ;

...to apply the state 'lazily' (ie to set only those things that
SSG *thinks* need to be changed) - or if you are deep ing
state-hell:

  mystate -> force () ;

...to force SSG to set every single itty-bitty state element to
this state's setup.

You also might want to check out the new ssgContext stuff.  It's
in the new online manual.
