energese 0.1.0

Initial CRAN release.

What’s here

• First R grammar-of-graphics library for H.T. Odum’s Energy Systems Language (ESL) — also known as Energese.
• 10 exported ggproto Geoms matching Wikipedia’s canonical Energese reference chart (https://commons.wikimedia.org/wiki/File:Energese.jpg): geom_odum_source(), geom_odum_flow(), geom_odum_storage() (Bertalanffy module), geom_odum_consumer(), geom_odum_interaction() (chevron), geom_odum_producer() (bullet), geom_odum_switch() (bowtie), geom_odum_self_limiter() (semi-circle), geom_odum_heat_sink() (arrow + ground line), geom_odum_transaction() (elongated diamond).
• Matching low-level odum_* vertex-tibble helpers for direct geom_polygon() composition or non-ggplot renderers.
• plot_energese_reference() — reproduces Wikipedia’s Energese chart directly from R.
• Vignette with worked examples: symbol legend, simple ecosystem, interaction junction, small economic system with money transaction.
• README + inst/CITATION with the canonical Odum + Brown references.
• Prior-art scan: to the author’s knowledge, this is the first R (or Python) grammar-of-graphics ESL library.
