Actually corr.test is even better than corr.model.
Use of 'corr.sim' instead of 'sigma' in GUI.
Options for saving config files.
Roxygenize.
Load example graph in Eclipse for faster development/testing.
Revert "Removing unused Class."

This reverts commit fda1ea8985d2c74bcbbfd5af8530babd88abd23e.
Options for config files move from PowerDialog to super class PDialog.
Removed buttons and code to change the correlation matrix used for testing.
Removed unnecessary gMCP::: prefixes.
Documented `...` for backward compatibility.
Introduced parameter `na.allowed` to function `checkCorrelation`.
Fixed backward compatibility for `sigma` and `cr`.
Check whether cv.getSigma() contains NAs.
Misspecification not any more allowed in GUI - but workflow should be much cleaner!!
Correlation matrices are saved to specific elements for the number of nodes of the graph and only loaded if the node size is the same.
MarginalPowerPanel - still not sure how/where to call it.
Parameter 'upscale' has now a complicated default for backward-compatibility: upscale=ifelse(missing(test)&&!missing(correlation)||!missing(test)&&test=="Bretz2011"
Updated ToDo.
Changed default alpha from 0.05 to 0.025.
Using SwingUtilities.isRightMouseButton fixes button mix-up.
