            * doc/uguide/surface.tex: Now using symbol_defs more heavily. Some
            changes to be consistent with rte_basic.tex.

            * src/methods.cc: Gin-variable of refellipsoidOrbitPlane had a
            name inconsistent with header text.

            * doc/uguide/rte.tex: Revised. Made consistent with rte_basic.tex
            and using symbol_defs throughout.

            * doc/uguide/symbol_defs.tex: Introduced emission soure and
            general source vectors, and transmission matrix. And changed the
            symbol for the Stokes vector to small i, to be consistent with all
            other vectors.

            * doc/uguide/rte_basics.tex: Now strictly following symbol_defs.

            * doc/uguide/rte_basics.tex:
            * doc/uguide/complete_calcs.tex:
            * doc/uguide/atmosphere.tex: Smaller fixes after a quick reading
            of these chapters.
