ExoColumn v1.0.0

First public release, accompanying Haqq-Misra, Wolf & Kopparapu (submitted to ApJ), "Validation of Habitable Zone Limits with a New Radiative-Convective Equilibrium Climate Model."

ExoColumn is a one-dimensional radiative–convective equilibrium model for planetary atmospheres, built on the ExoRT correlated-k radiation core that also drives ExoCAM. It couples an independently developed column physics package to ExoRT without modifying it, so spectroscopic updates propagate automatically.
