Changes in Version 1.6
    - Changed the way the pairwise, minimum and maximum sample sizes are computed for estimators using a correlation matrix as input with missing data. Thanks to Carl Falk. This might lead to different results compared to older bootnet versions! To recover old results, use the "pairwise_average_v1.5", "pairwise_minimum_v1.5", and "pairwise_maximum_v1.5" arguments in the sampleSize argument of the default functions.

      - All default functions are now by default locked unless used from within estimateNetwork

      - Added bootInclude function to obtain a network of bootstrap inclusion probabilities
      - the 'statistics' argument in bootnet now defaults to c("edge","strength","outStrength","inStrength"). This means that closeness and betweenness are no longer stored by default!

      - Included the 'includeDiagonal' argument to bootnet to include storing diagonal entries (self-loops) for directed networks only
      - Bootnet now copies the library used by the user to the clusters when using nCores > 1. This is important for checkpoint and packrat compatability
      - corStability now returns NA for incomputable correlations (e.g., due to infinite values)
  o Experimental:
      - Added default set "piecewiseIsing" for estimating Ising models while selecting participants on a sum-score (very experimental)

  - plot method now supports split0 = TRUE, will show how often an edge was 0 and only show CIs of non-zero estimates (faded relative to proportion of times edge was zero).
