Major strategy update

Very early prototype version.

Player begins with $400, Computer starts with buildings.

• Click on green spots to build buildings there for $100 each.

Financial buildings (picture is cluster of skyscrapers) increase income by $5/tick.

Factory building spawns attacking units. Each unit costs money. Will implement player choice of which units to spawn in near future...

Tower building destroys incoming attackers. No animation but enemy units will disappear when in range.

• Click on a building to:

[Up arrow] upgrades the building for $100. There is no UI change but it works, trust me. Level multiplies building effect i.e. financial building level 2 provides $10/tick, Tower building increases rate of fire, factories spawn more units if money is available.

[horizontal line] toggles unit spawning on that factory. Useful when saving money for other buildings. No effect for other buildings.

[X/* thing] no effect currently. Will be an option to delete a building so it can be replaced.
