In europepmc: R Interface to the Europe PubMed Central RESTful Web Service

#' europepmc - an R client for the Europe PMC RESTful article API
#'
#' @description What is europepmc?:
#'
#' europepmc facilitates access to Europe PMC RESTful Web Service. Europe
#' PMC covers life science literature and gives access to open access full
#' texts. Coverage is not only restricted to Europe, but articles and
#' abstracts are indexed from all over the world. Europe PMC ingests all PubMed
#' content and extends its index with other sources, including Agricola, a
#' bibliographic database of citations to the agricultural literature, or
#' Biological Patents.
#'
#' Besides searching abstracts and full text, europepmc can be used to
#' retrieve reference sections and citations, text-mined terms or cross-links
#' to other databases hosted by the European Bioinformatics Institute (EBI).
