- Allows to print the covariance matrices of the gaussian mixture model

- Can be used to increase the number of data points for model training

- Suppressing an integer comparison warning

- Implemented "means" REST API action

- A plugin based on gaussian mixture models to enable clustering for
performance variation analysis or outlier detection
