Synopsis

This class is derived from TableExprGroupFuncBase and acts as the abstract base class for aggregate functions resulting in a string array.
Derived classes can use itsValue to contain the aggregated value. It that case they do not need to implement the get function.

If not empty, check if the shape matches that of itsValue.

If itsValue is still empty, it is sized.
