Increasing Research Costs and Harder Eurekas

This mod increases Tech- and Civic- Costs and makes Eurekas harder to get. Later Eras have a higher increase of Research Cost.
The main purpose of this mod is to give you enough time for productions and time for wars without having to fear that your army gets outdated very soon. At the same time the costs are balanced in a way that your research should roughly match the current date of year (e.g. you should be researching Techs in the Industrial Era when you are in a year between 1800 and 1900 A.D.).

If you also want higher Great Person costs you can use this mod together with
More Great Persons + GP Cost Balancing, but it is not necessary.

The Research Costs for Techs and Civics are multiplied in the following way:

• Ancient Era: Cost x1.4
  
• Classical Era: Cost x1.7
  
• Medieval Era: Cost x2.1
  
• Renaissance Era: Cost x2.5
  
• Industrial Era: Cost x3.1
  
• Modern Era: Cost x3.8
  
• Atomic Era: Cost x4.6
  
• Information Era: Cost x5.6
  
• FutureEra: Cost x6.8

The research boosts from some of the Great Scientists (like Galieo Galiei) are scaled accordingly.

The Code of Laws Civic Cost has been additionally multiplied with 1.5 to make monuments more important, if you do not want to get certain Ancient Civics too late.

Note: If your Science and Culture output is not too small, you will need roughly about 20 turns for researching a Tech or Civic without an Eureka (and about 10 turns with an Eureka).
I have tested this mod a lot on Standard Speed, so do not fear the high Research Costs. It is well balanced.

Many Eurekas are now harder to get. You can still get most of the Eurekas if you try hard, but dependent on your strategy or your starting location you still may not get all of them.
For example the Eureka for Horse Back Riding requires 3 pastures, Steam Power require 3 Shipyards, Urbanization requires a City with 20 Population, etc.

You do not have to own Rise and Fall, but for R&F owners the following changes are made:

• The needed base points for entering a Normal Age is increased to 15 (instead of 12). For Great Ages the points is increased to 30 (instead of 24). This change is due to the longer durations of eras because of the increased research cost.
  
• The minimum and maximum turns of the era durations are now dependent on how much technologies are available in the particular Era. The values in the table below are for the normal game speed:
