Added global counter description
"* **TextLogger**: This logger, mostly intended for file logging, is the plain text version of the `InteractiveLogger`. Keep in mind that it may be very verbose.\n",
"* **TensorboardLogger**: It logs all the metrics on [Tensorboard](https://www.tensorflow.org/tensorboard) in real-time. Perfect for real-time plotting.\n",
"\n",
+ "In order to keep track of when each metric value has been logged, we leverage a `global counter`. You can see the `global counter` reported in the x axis of the logged plots.\n",
+ "\n",
+ "The `global counter` is an ever-increasing value which starts from 0 and it is increased by one each time a training or evaluation iteration is performed (i.e. after each training or evaluation minibatch).\n",
+ "The `global counter` is updated automatically by the strategy. It should be reset by creating a new instance of the strategy.\n",
+ "\n",
