Master of Orion/Comparative tree

The following is a listing of all of the techs, by level, so people don't have to jump between different tech fields when comparing techs in terms of trading

Blue squares indicate techs that are almost always or always available. All techs will be listed in the order of Computers, Construction, Force Fields, Planetology, Propulsion, and Weapons. No field has techs in all levels so levels with more and less are expected.
