MPTmultiverse 0.4-1

• Adapted MPTinR unit tests for no pooling approaches to fail even less with R 4.0.0.

MPTmultiverse 0.4-0

• Added a NEWS.md file to track changes to the package.
• Added within-subjects comparisons of parameter estimates that are stored in column test_within of the results object.
  • For the Bayesian methods, these comparisons rely on posterior distributions of parameter differences.
  • For the no-pooling maximum-likelihood methods, comparisons rely on paired t tests.
  • For the complete-pooling maximum-likelihood method, comparisons rely on the the point estimates of parameters and the estimates of the standard errors of differences calculated from the Hessian matrix.
• Changed the default behavior for auto-extending Bayesian models: As of now, chains are only combined if Rhat <= Rhat_max*2-1. An informative message is printed whether chains were combined with earlier draws or not.
• Prepared MPTmultiverse for new tibble version.
