/**
* Handles <ds:Signature> elements.
* This is the main class that deals with creating and verifying signatures.
*
* There are 2 types of constructors for this class. The ones that take a
* document, baseURI and 1 or more Java Objects. This is mostly used for
* signing purposes.
* The other constructor is the one that takes a DOM Element and a baseURI.
* This is used mostly with for verifying, when you have a SignatureElement.
*
* There are a few different types of methods:
*
- The addDocument* methods are used to add References with optional
* transforms during signing.
* - addKeyInfo* methods are to add Certificates and Keys to the
* KeyInfo tags during signing.
* - appendObject allows a user to add any XML Structure as an
* ObjectContainer during signing.
* - sign and checkSignatureValue methods are used to sign and validate the
* signature.
