/**
 * The FormScheme class implements the AuthScheme interface to provide
 * form-based authentication for HTTP clients. It handles the process of
 * obtaining a token and logging in using the provided credentials.
 *
 * <p>This class supports both GET and POST methods for token and login
 * requests. It also allows for the replacement of placeholders in URLs and
 * parameters with actual credentials.
 *
 * <p>Usage example:

* «the engine»: «die Engine»
* «the error response»: «die Error-Response»
* «the event»: «das Event»
* «the exception»: «die Exception»
* «the exception handler»: «der Exceptionhandler»
* «the form model»: «das Formularmodell»
* «the form body»: «der Formularbody»
* «the header»: «der Header»
* «the headers» (plural): «die Header»
* «in headers» (plural): «in Headern»
* «the forwarded header»: «der Forwarded-Header»

/// note

It doesn't matter what you type in the form, it won't work yet. But we'll get there.

///

This is of course not the frontend for the final users, but it's a great automatic tool to document interactively all your API.
