This mod change research cost for all technologies in the game.
All specialization technologies are 80% of it's mother technology. Next level technology is alway's higher then it's previus technology. I tried to have it 2,5 times higher, but it can be as low as 1,75 times higher.
All tech trees reserach cost are higher. The top level technologies are as hard to get as weapon technologies. With accension technologies as the hardest to get.

I made two types of tech files, the first is named:

TechFixVanilla
--------------
    Start and top level values are close to normal game.


TechFixVanillaPlus
------------------
    Start level is the same as normal game, top level is logaritmicly higher. about 1000 points
