//! Write a Bild file with the geometry
/** The bild file format is a simple format for displaying geometry in Chimera.
    The bild writer supports points, spheres, cyliners, and segments.

    You are probably better off using the IMP::display::ChimeraWriter unless
    you want a human-readable file. ChimeraWriter supports better
    interactivity and more types of geometry.
