Notes
Level is the technology level.
ID is the level / application ID.
Requires states any prior research that must have been done prior to researching a given
technology. Note, the base level technology must always be researched prior to researching any
application within that level.
Allows means this technology is required for the listed technologies.
Name is the name used in game. Really, it's from the comment in the tech file.
Effects are adjustments put into effect when a technology is researched.
The source file for this information is ..\DB\Tech\nuclear_tech.txt
