Description: Queries the 'NCBI' (National Center for Biotechnology Information)
    Entrez 'E-utilities' API to count pairwise co-occurrences between two sets
    of terms in 'PubMed' or 'PubMed Central'. It returns a matrix-like data
    frame of publication counts and can export hyperlink-enabled results in
    CSV or ODS format. The package also provides heatmap helpers for
    exploratory visualization of overlap patterns. Based on the method described
    in Becker et al. (2003) "PubMatrix: a tool for multiplex literature mining"
    <doi:10.1186/1471-2105-4-61>.
