I've now implemented the cohort level feature extraction.
Per CategoryType, DataItems are extracted per sample and inserted into DataItemMatrix (n_features x n_samples; a ConcurrentHashMap) using [DataSource,ItemType,Key] attributes from DataItem as the keys. Once all samples are processed, DataItemMatrix is written to a file.
Multithreading is based on TaskExecutor. I copied the code in SampleTask and CupAnalyzer.
