farm require neighboorhood information between farms and cities,
which is not yet encoded.
end game scoring is not yet implemented

pennants, inns, cathedrals

detecting adjacent parts of a structure and lack thereof will be used
to tell whether a structure is completed

impossible means the piece can not be placed on the
current board due to collisions in all free places

free means adjacent to another piece but not containing a piece

actually remove start piece from pieceOrder

i suppose i only tested with pointer accumulators before

don't modify pointer members of Place
any modifications must be done by copying and
publishing via board.Set to be atomic

assembling the byte slices for each block is the most
computation time consuming action. Keep ready made
slices for checker board blocks and unmodified blocks
from pieces (i.e., no follower, no underline separator, no highlight)

draw underscores on board pieces if current piece is held
below board piece

draw everywhere on boardview, have bounding box enclose placeable area

34 was not blue, also don't user magic constant

board needs to be threadsafe unless
we want to make it part of the states and copy it on each keypress

board is not expanded, placement is not checked for bounds or game
rule conformity

parse piece definitions from files
render randomly drawn piece on agents turn
board not writable yet
