top.js:
SHORTCUTS showBusy("caller id"); showBusyOff("caller id");
	GENERALLY put showBusy() in orig func(), then setTimeout 10 for func2().
  function makeBusySpt() {...} echo's BUSY and refreshes.
	function makeBusyOffSpt() {...} blanks middle echo, refreshes, messages BusyOff.

makeView1Spt() (in scripts.js) ends with makeBusySpt()

initializeSecondaryStructureSpt() includes makeBusyOffSpt()

doMolViewSpt() in scripts.js
	calls scriptToJmol() which is in top.js
		which does showBusy() and after a tiny setTimeout() 
		scriptToJmol2()** BUSY ON/OFF **
			calls unchangedScriptToJmol()

**scriptToJmol() (in top.js) calls showBusy(caller)
	which prepends makeBusySpt() when !usingJava and currentView is not renderend
    (meaning currentView is not rendering of the end of a chain)
  and postpends makeBusyOffSptNoRefresh() UNLESS cancelcenteringhidingprecontacts †

†Before this conditional,
CatpiSB was failing to show busy after help was displayed (6ef8).
