  - adds support to sparse matrix input in the form of dgCMatrix

                 Changes in version 1.1.1 (2020-09-17)

    throw an error

                        Changes in version 1.1.0                        

  - fit exposes max_depth parameter with default value of
    ceiling(log_2(sample_size))
  - path length extension is not done anymore (Thanks to karthi1870)
  - ranger's forest object is now public
  - fit checks for duplicates in the input dataset

                 Changes in version 1.0.1 (2020-07-07)                  

  - finalized on the API
  - isolationForest object no longer calculates and stores anomaly
    scores on training data. Use predict method for this.
  - mtry is no longer exposed
  - version 1.0.0 was a faulty release, do not use it

                 Changes in version 0.2.1 (2019-12-07)                  

  - added 'mtry' argument for isolationForest method
  - minor optimizations in 'terminalNodesDepth' function

                 Changes in version 0.2.0 (2019-08-24)                  

  - Changes in API: isolationForest is now a R6 class with new(), fit()
    and predict() methods.
  - Exported terminalNodesDepth function to obtain the depth of terminal
    nodes of all trees in a ranger forest.

                 Changes in version 0.1.3 (2019-06-05)                  

  - Changed defaults to avoid bagging in extremely randomized trees (see

  - Using future_lapply in favor of furrr::furrr_map
