- Make match method testable.

- Class is immutable and this returns a new object with the
new configuration. This allows us during bootstrap to change this before passing it to loadspkr modules.

- Make class use of config more predicable by stop using
global conf.
- Make the class vital methods more testable.

- Allow us to inject a configuration to class and enable us to test it before
refactoring.

Makes it easier to replace the use of global throughout the code.

- Reformatting
- Error 500 exits. Will never return.

- Easier to maintain without all errors.

Enable us to replace global states.

- Inject this into the needed classes and get
away from globals.

Do not implement properties or code. It is a interface
and should be typed as one.

- Also remove extra include of settings. No longer needed.

- Composer PSR-4 autoloading.

- Reduce logic complexity.
- Return early. Code get called on every request and should be fast.
- Remove support for mirroring multiple uri. Code uses a long gone
PHP function. Split this into a private method.

- Also require the file. Force it to fail hard if not found.

Cleanup that improve code readability.

First thing application do is loading the settings making sure
that it is available.

We cannot just remove data from common.inc.php
The class expect and try to use it throwing errors/warning every
time the application load.

- No need to waste time calling Utils::uri2curie()

- Use PSR-4 autoloading
- Clean up code and reduce complexity.

- Paves way for real autoloading in the future.

- Always called utilities. We need to make sure they work
as expected. Introduce PHPUnit tests.
- Due to the use of gobals inside the static methods they
become untestable. Remove use of global but that also
forces a change if method signature.
