@spec default_config() :: map()

Get default config of library.

@spec start() :: :ok

Start with default config.

In this case, library just uses Logger to log data in every event.

@spec start(%{:worker => non_neg_integer(), optional(any()) => any()}) :: :ok

Start with config.

The config is a map type.

Config has info like:

  %{
    worker: 3,  # number of worker will run
    event: 100, # number of GPS events will be trigger for a worker
    interval: 1000, # this & random_range used for sleep between GPS events, if value is :infinity worker will run forever (you still stop by return {:stop, reason})
    random_range: 0, # 0 mean no random, other positive will be used for generate extra random sleep time
    callback: MyCallbackModule # your module will handle data
  }

:id is reserved for worker's id.

If you need pass your data to callback module you can add that in the config.

The config can be change after every event.
