ESMF_HConfigFileLoad Subroutine

  subroutine ESMF_HConfigFileLoad(hconfig, filename, keywordEnforcer, doc, rc)
!
! !ARGUMENTS:
    type(ESMF_HConfig), intent(in)            :: hconfig
    character(len=*),   intent(in)            :: filename
type(ESMF_KeywordEnforcer), optional:: keywordEnforcer ! must use keywords below
    integer,            intent(in),  optional :: doc
    integer,            intent(out), optional :: rc
!
! !DESCRIPTION:
!   Load YAML file into {\tt hconfig}.
!
!   The arguments are:
!   \begin{description}
!   \item[hconfig]
!     {\tt ESMF\_HConfig} object.
!   \item[filename]
!     Name of the YAML file to be loaded.
!   \item[{[doc]}]
!     The doc index inside the file. If specified, only this single document
!     is loaded from file, resulting in a single document {\tt hconfig} object.

!   \item[{[rc]}]
!     Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
