/*

As the log statement says, this module does nothing to persist your data
|
||||
across sessions. If your process crashes for any reason, all pads will die.
|
||||
|
||||
This might be useful if you want to debug other parts of the codebase, if
|
||||
you want to test out cryptpad without installing mongodb locally, or if
|
||||
you don't want to rely on a remote db like the one at mongolab.com.
|
||||
|
||||
Maybe you just like the idea of a forgetful pad? To use this module, edit
|
||||
config.js to include a directive `storage: './storage/amnesia'
|
||||
|
||||
Enjoy!
