Caveat emptor: this is a work in progress and does not currently support all shapefile geometry types. It only supports dBASE III and has little error checking. Please contribute if you want to help!

 In-browser parsing of dBASE table files requires [TextDecoder](https://developer.mozilla.org/en-US/docs/Web/API/TextDecoder#Browser_compatibility), part of the [Encoding living standard](https://encoding.spec.whatwg.org/), which is not supported in IE or Safari as of September, 2016. See [text-encoding](https://github.com/inexorabletash/text-encoding) for a browser polyfill.
