class_docstr: DmlCorpus implements a collection of articles. It is initialized via a DmlConfig
  object, which holds information about where to look for the articles and how
  to process them.
  
  Apart from being a regular corpus (bag-of-words iterable with a `len()` method),
  DmlCorpus has methods for building a dictionary (mapping between words and
  their ids).
docstr: Store the corpus to disk, in a human-readable text format.
  
  This actually saves multiple files:
  
  1. Pure document-term co-occurence frequency counts, as a Matrix Market file.
  2. Token to integer mapping, as a text file.
  3. Document to document URI mapping, as a text file.
  
  The exact filesystem paths and filenames are determined from the config.
