Consider re-exporting geo_types so this crate can be used without additional dependencies

[AlanRace]

I would like to use this crate without further dependencies (I only need the union functionality really). I can do this currently if I modify the first line of /lib/src/boolean/mod.rs to:

pub use geo_types::{Coordinate, LineString, MultiPolygon, Polygon};

As an aside, I tried just using the latest version of geo_types in addition to this crate in my Cargo.toml and it failed to import/recognise the BooleanOp trait on the Polygon type. The above would also resolve this issue (unless there's something obvious I am missing?).

Possibly due to a mismatch in versions, causing duplicated geo-types in your dependency tree. You can check with cargo tree -d and see if geo-types appears with two different versions.

The above would also resolve this issue (unless there's something obvious I am missing?).

I think you're right that it'd resolve your immediate issue: you'd be able to use boolean-ops on the geometries exported from this crate, but since it sounds you are using another crate which relies on an incompatible geo-types, you might just have a similar issue somewhere else.

The thing I usually want, and somewhat commonly stumble at, is to get all my crates depending on the same version so they can interop.

See also #33 which updates this crate to use the latest geo-types.
