<p>Represents a set of source artifacts, a set of target artifacts,
and a ground truth model that represents the links between them.
NOTE: This assumes that artifacts separated by line in the same file begin with
an ID. Thus, the first word of every line will not be considered part of the artifact
for semantic purposes
Attributes:
    _name (str): The identifier of the corpus dataset
    _corpus_root (str): Path to the root directory of the corpus, from
        which the source, target, and truth files will be derived
    _sources (list of str): one str per artifact
    _targets (list of str): one str per artifact
    _truth (dict of str:(dict of str:int)): Holds the truth values of links
        between sources and targets. _truth[source][target] == 1 if link exists,
        0 otherwise.
    _source_index (list of str): aligned with source so that source_index[i]
        contains the filename or identifier for source[i]
    _target_index (list of str): aligned with target so that
        target_index[i] contains the filename or identifier for target[i]
    _filetype_whitelist (list of str): See <strong>init</strong> documentation
    _filetype_blacklist(list of str): See <strong>init</strong> documentation</p>
