Description: Draws forest plots of exposure effects from fitted
        regression models. Name an exposure and 'foresty' plots its
        effect. Name an effect modifier as well and it refits the model
        with the interaction term, estimates the exposure effect within
        each level of the modifier as a linear combination of the
        coefficients, and reports the joint interaction test beside
        those estimates. It takes one exposure and one modifier at a
        time, so the interaction is always a two-way one. Rows of the
        plot and of the table beside it share one scale, in a layout
        that can follow a journal's house style. The same results go to
        a self-contained HTML page holding the subgroup estimates, the
        joint test and the coefficient table. The 'car' package
        computes the linear combinations and their tests. Models fitted
        by stats::glm(), stats::lm(), the 'survival' package, the
        'lme4' package, the 'geepack' package and the 'survey' package
        are supported, as is any fit supplying coef() and vcov().
        Ordinal outcomes are supported through the 'MASS' package and
        nominal ones through the 'nnet' package, where the figure
        carries one row per level of the outcome and the interaction is
        tested jointly across the equations. Fits from the 'rms'
        package are refused, naming the function that fits the same
        model in their place. The estimation of an exposure effect
        within a level of a modifier, and the test of the difference
        between such estimates, follow Altman and Bland (2003)
        <doi:10.1136/bmj.326.7382.219> and VanderWeele and Knol (2014)
        <doi:10.1515/em-2013-0005>; the reporting of subgroup effects
        beside the interaction test follows Wang et al. (2007)
        <doi:10.1056/NEJMsr077003>, and the figure itself the forest
        plot described by Lewis and Clarke (2001)
        <doi:10.1136/bmj.322.7300.1479>.
