Examples multiple-graphs-with-factory.php and multiple-graphs.php do not work

[kresimir71]

I have tested the examples.
Examples multiple-graphs-with-factory.php and multiple-graphs.php do not work.
Here is what we get.

php multiple-graphs-with-factory.php
PHP Fatal error:  Class 'Pimple' not found in vendor/yohang/finite/examples/multiple-graphs-with-factory.php on line 77

php multiple-graphs.php
PHP Fatal error:  Uncaught exception 'Symfony\Component\PropertyAccess\Exception\NoSuchPropertyException' with message 'Neither the property "finiteState" nor one of the methods "getFiniteState()", "finiteStat\
e()", "isFiniteState()", "hasFiniteState()", "__get()" exist and have public access in class "Order".' in vendor/symfony/property-access/PropertyAccessor.php:516
