Based on Proj4 implementation

The aim of Proj4rs is to provide at short term the same functionality as the original proj4 library.

The long term project is to integrate feature from the proj library in its latest version.

The goal of proj4rs is not to be a remplacement of proj, but instead beeing a light weight implementation of transformations from crs to crs that could be used in WASM environment

There is no actual support for WKT, if such supports would exist one day, it would be under a dedicated crate for transforming proj string to to WKT and vice-versa.

If you need full support for WKT, please rely on proj which provide a great implementation of the standard.
