-/**
- *
- * This is an open source decentralised communications
- * platform combined with a decentralised identity/authentication framework
- * wrapped in an extensible content management system, providing website designers
- * the ability to embed fully decentralised communications and social tools
- * into many traditional website designs (blogs, forums, small business
- * websites, charitable organisations, etc.). Also provided is DNS mobility
- * and internet scale privacy/access control.
- *
- * This allows any individual website to participate in a matrix of linked
- * sites and people and media sharing which is far greater than the reach
- * of an individual site.
- *
- * If you are reading the source code and come across a function
- * or code block which is not documented, but you have a good idea what it
- * does, please add some descriptive comments and push it to the main project.
- * Even if your description isn't perfect, it gives us a base which we
- * can build on and correct - so that eventually everything is fully
- * documented.
