    This will take the UCSC defintions of cytogenic bands and create the nested
    structures to enable overlap and containment queries. We use
    ```Monochrom.py``` to create the OWL-classes of the chromosomal parts.
    Here, we simply worry about the instance-level values for particular genome
    builds.

    Given a chr band definition, the nested containment structures look like:
    13q21.31 ==>  13q21.31,  13q21.3,  13q21,  13q2,  13q, 13

    We determine the containing regions of the band by parsing the band-string;
    since each alphanumeric is a significant "place", we can split it
    with the shorter strings being parents of the longer string

    Here we create build-specific chroms, which are instances of the classes
    produced from ```Monochrom.py```.
    You can instantiate any number of builds for a genome.

    We leverage the Faldo model here for region definitions,
    and map each of the chromosomal parts to SO.

    We differentiate the build by adding the build id to the identifier prior
    to the chromosome number.
    These then are instances of the species-specific chromosomal class.

    The build-specific chromosomes are created like:
    <pre>
    <build number>chr<num><band>
    with triples for a given band like:
    :hg19chr1p36.33 rdf[type] SO:chromosome_band, faldo:Region, CHR:9606chr1p36.33
    :hg19chr1p36.33 subsequence_of :hg19chr1p36.3
    :hg19chr1p36.33 faldo:location
        [ a faldo:BothStrandPosition
                faldo:begin 0,
                faldo:end 2300000,
                faldo:reference 'hg19']
    </pre>
    where any band in the file is an instance of a chr_band
    (or a more specific type), is a subsequence of it's containing region, \
    and is located in the specified coordinates.

    We do not have a separate graph for testing.

    """
    The Comparative Toxicogenomics Database (CTD) includes curated data
    describing cross-species chemical–gene/protein interactions and
    chemical– and gene–disease associations to illuminate molecular mechanisms
    underlying variable susceptibility and environmentally influenced diseases.

    Here, we fetch, parse, and convert data from CTD into triples,
    leveraging only the associations based on DIRECT evidence
    (not using the inferred associations).
    We currently process the following associations:
        * chemical-disease
        * gene-pathway
        * gene-disease

    CTD curates relationships between genes and chemicals/diseases with
    marker/mechanism and/or therapeutic.
    Unfortunately, we cannot disambiguate between marker (gene expression) and
    mechanism (causation) for these associations.  Therefore, we are left to
    relate these simply by "marker".

    CTD also pulls in genes and pathway membership from KEGG and REACTOME.
    We create groups of these following the pattern that the specific pathway
    is a subclass of 'cellular process' (a go process), and the gene is
    "involved in" that process.

    For diseases, we preferentially use OMIM identifiers when they can be used
    uniquely over MESH.  Otherwise, we use MESH ids.

    Note that we scrub the following identifiers and their associated data:
    * REACT:116125 - generic disease class
    * MESH:D004283 - dog diseases
    * MESH:D004195 - disease models, animal
    * MESH:D030342 - genetic diseases, inborn
    * MESH:D040181 - genetic dieases, x-linked
    * MESH:D020022 - genetic predisposition to a disease
