Crate for working with [https://www.websequencediagrams.com/](https://www.websequencediagrams.com/)
 public [RESTful API](https://www.websequencediagrams.com/embedding.html)
 This service allows to create sequence diagrams from simple text.
 Note: this library is a simple wrapper around the API.
 Some features of this service require premium subscription (like export to pdf format)
 Features supported by this library
 * statically typed library. Different options are represented as enums
 * multiple output formats: png, pdf (premium), svg (premium)
