/*
|
||
* TODO combine this header and its CPP file with editor/editor_storage.hpp and its CPP counterpart,
|
||
* give it an appropriate namespace and place it where both editor and traffic can use it.
|
||
* `traff_storage` is essentially copied from `editor_storage` with just a few modifications:
|
||
* - namespace
|
||
* - instead of relying on a hardcoded file name, `LocalStorage` is initialized with a file name
|
||
* - log output, variable names and comments changed to be use case neutral (no API changes)
|
||
* - refactoring: no global `using namespace` (no API changes)
|
||
* Apart from the first two points, this file can serve as a drop-in replacement for `editor_storage`.
|
||
* Traffic uses only `LocalStorage`, the rest has been kept to ease migration to a unified storage
|
||
* component.
