## Example

To configure and run a monitor that watches for file changes to update an in-memory config store:

```golang
// Configure the config store
store := memory.Make(configDescriptor)
controller = memory.NewController(store)
// Create an object that will take snapshots of config
fileSnapshot := configmonitor.NewFileSnapshot(args.Config.FileDir, configDescriptor)
// Provide snapshot func to monitor
