hex map

drawing

define hex map in terms of rows/columns, calculate multiplier from there

Also split out x vs y multiplier

modeling

use cl-graph to model the hexmap

1. after drawing

   build up row/column and x/y for each hex, then loop over building vertex/edges afterwards?

2. before drawing use the row/col limits to generate the graph first, then walk the graph to draw the map?

interaction

highlight a hex on mouseover

highlight hexes with a given radius

source code

refactor in /src folder

use unwind-protect in with-hexmap

tests?

logging framework
