Forest plot package

The forestplot package enables the creation of advanced forest plots, offering features such as multiple confidence intervals per row, customizable fonts for individual text elements, and custom confidence interval drawing functions. Additionally, it supports text mixed with mathematical expressions, extending the use of forest plots beyond traditional meta-analyses. This package is a more general version of the original 'rmeta' package's forestplot function, with heavy reliance on the 'grid' package for graphical elements.

One of the newer features is the ability to have text span multiple table columns via the fp_span() helper, making it easy to centre sub‑headers across adjacent columns. The label system has also been hardened so that you can include arbitrary grid grob objects in labeltext; they will be plotted in the appropriate cell without triggering errors.
