FIRM: Initial Release

FIRM is a Federated Information Resource Manager. It's a flexible server platform for experimentation with ActivityPub and Social Web software. The focus is not on performance or scalability, but on the ability to create rapid prototypes of new functionality.

This is a work in progress so expect bugs and breaking changes. The source code is being released for those brave souls who are curious enough to explore the implementation details.
