Declare blocks not yet implemented

[johnperry-math]

To the following code:

declare
   Neighbors: Natural := 0;
begin
   --  stuff
end;

...HAC replies:

src/day04.ada: 61:16-22: construct not yet implemented or supported by HAC: Block statements don't work yet

I am reporting this as something "to do", unless the developers consider it not worth doing.
