Role: Auxiliary script
Content type: text/plain
Description: Auxiliary script
Class: Chronicle
Append arbitrary data to a storage container
Author: By
Last change: Add helper method for determining valid instance names.
Fix settings loading
Concurrent Chronicles

Add support for multiple instances via the ?instance=name parameter.

To implement, add something like this to your local/settings.json in the
instances key:

"public_prefix" => "table_name_prefix"

Then run bin/make-tables.php as normal.

Every instance is totally independent of each other. They have their own

* Clients
* Chain data
* Cross-Signing Targets and Policies
* Replications

If merged, I will document these features and roll it into v1.1.0
