Improve the CI test plots

[ankurankan]

Proposed Changes:

1. More descriptive names of the DGM in the drop down menu.
2. For a given DGM, each CI test should be a line in the plots.
3. CI Test, effect size, and Significance level selection boxes should be removed.
4. A Sample size selection box should be added.
5. The Calibration plot should be: Type 1 error vs significance level, where the significance level varies from 0 to 1. In the significance plot, each line should represent one CI test.
6. The power plot should be: power vs effect size. The effect size should vary from 0.2 to 1. The significance level for the power plot should be fixed to 0.05. There should be lines for each CI test for the DGM.
7. Each row of plots should have the calibration and power plot for a specified sample size.
8. For each DGM, also show the equation for the DGM above the plots.
