//
// Integration test of the geo code
//
// Basically, this tests adds a random number of docs with a random number of points,
// given a 2d environment of random precision which is either randomly earth-like or of
// random bounds, and indexes these points after a random amount of points have been added
// with a random number of additional fields which correspond to whether the documents are
// in randomly generated circular, spherical, box, and box-polygon shapes (and exact),
// queried randomly from a set of query types. Each point is randomly either and object
// or array, and all points and document data fields are nested randomly in arrays (or not).
//
// We approximate the user here as a random function :-)
//
// These random point fields can then be tested against all types of geo queries using these random shapes.
//
// Tests can be easily reproduced by getting the test number from the output directly before a
// test fails, and hard-wiring that as the test number.
//
