// Description:
// This code takes those buildings out of the build lists of both AI and
// human players that are no longer necessary because a Wonder was built by
// this player that gives a free building of this type in every city. This
// prevents the AI from building expensive buildings that it doesn't need
// anyway and makes the build list more readable and less confusing for the
// human. When wonders are lost or go obsolete, the buildings reappear in the
// build lists.

// make buildings unbuildable for civs with a wonder that grants those buildings
