returnValue UnaryOperator::loadIndices ( SymbolicIndexList * indexList )

The function loadIndices passes an IndexList through
the whole expression tree. Whenever a variable gets the
IndexList it tries to make an entry. However if a
variable recognices that it has already been added
before it will not be allowed to make a second entry.
Note that all variables, in paticular the intermediate
states, will keep in mind whether they were allowed
to make an entry or not. This guarantees that
intermediate states are never evaluated twice if they
occur at several knots of the tree.

THIS FUNCTION IS FOR INTERNAL USE ONLY.

AS A KIND OF INIT ROUTINE.

Returns: the name of the expression.
