KstEquation::setEquation is called internally from other methods in 

KstEquation::setEquation is also called from KstEqDialogI where the equation 
object is locked previously.  Locking the equation object locks all the 
inputScalars associated with it and then setEquation unlocks all of them, 
clears them, reparses the equation, and adds the newly found equations 
scalars.  These scalars need to be relocked because 
KstEqDialogI::editSingleObject() will eventually unlock the equation object 
which necessarily unlocks all the _inputScalars.

I'm thinking the proper fix is to use a ScalarsUsed map like KstEquation's 
current VectorsUsed map.
