   Couple of notes, let me know what you think:
   - I've added an extra dot to data generation scripts, to go back a 
directory, if the command is "systemds". This is done to compensate the 
different folder structure of the perftests when ran locally, instead of on a 
cluster.
   - I'm assuming the federated tests are to be ran locally only, not on a 
cluster.
   - The stratified statistics benchmark needs a heap size of at least 10 GB. 
This setting is exported only when it's ran locally via "export 
SYSTEMDS_STANDALONE_OPTS="-Xmx10g -Xms10g -Xmn2000m"
   - The K-means built-in function does a predict implicitly, meaning the 
benchmark predicts twice, as of now.
   - Could not get the decision tree training built-in function to run. 
       - It does not stop when ran with logistic regression data. 
       - There are scripts to generate decision tree data, but these can not be 
ran either as the built-in transform function does not exist anymore, 
apparently.
   - Could also not get the old decision tree and random forest algorithms 
running without looking deeper into it. (null pointer exception)
