/**
* Stores the validator's state during validation.
*
* For example, let's validate the following object graph:
*
* <pre>
* (Person)---($firstName: string)
* \
* ($address: Address)---($street: string)
* </pre>
*
* We validate the <tt>Person</tt> instance, which becomes the "root" of the
* validation run (see {@link getRoot}). The state of the context after the
* first step will be like this:
*
* <pre>
* (Person)---($firstName: string)
* ^ \
* ($address: Address)---($street: string)
* </pre>
*
* The validator is stopped at the <tt>Person</tt> node, both the root and the
* value (see {@link getValue}) of the context point to the <tt>Person</tt>
* instance. The property path is empty at this point (see {@link getPropertyPath}).
* The metadata of the context is the metadata of the <tt>Person</tt> node
* (see {@link getMetadata}).
*
* After advancing to the property <tt>$firstName</tt> of the <tt>Person</tt>
* instance, the state of the context looks like this:
*
* <pre>
* (Person)---($firstName: string)
* \ ^
* ($address: Address)---($street: string)
* </pre>
*
* The validator is stopped at the property <tt>$firstName</tt>. The root still
* points to the <tt>Person</tt> instance, because this is where the validation
* started. The property path is now "firstName" and the current value is the
* value of that property.
*
* After advancing to the <tt>$address</tt> property and then to the
* <tt>$street</tt> property of the <tt>Address</tt> instance, the context state
* looks like this:
*
* <pre>
* (Person)---($firstName: string)
* \
* ($address: Address)---($street: string)
* ^
* </pre>
*
* The validator is stopped at the property <tt>$street</tt>. The root still
* points to the <tt>Person</tt> instance, but the property path is now
* "address.street" and the validated value is the value of that property.
*
* Apart from the root, the property path and the currently validated value,
* the execution context also knows the metadata of the current node (see
* {@link getMetadata}) which for example returns a {@link Mapping\PropertyMetadata}
* or a {@link Mapping\ClassMetadata} object. he context also contains the
* validation group that is currently being validated (see {@link getGroup}) and
* the violations that happened up until now (see {@link getViolations}).
*
* Apart from reading the execution context, you can also use
* {@link addViolation} or {@link addViolationAt} to add new violations and
* {@link validate} or {@link validateValue} to validate values that the
* validator otherwise would not reach.
