Made a mistake when uploading to pypi

README.md with proper examples

Added Metric.calculate() with a docstring

Bugfixes:
- data for calculating metrics in Runner.run_reporters was not sent to torch.device
- steps were not incremented properly for TensorboardScalarReporter

Added a working example in example_alexnet_mnist.py
Added CrossEntropy as a new Metric

Updated README.md

Reworked reporters and metrics, and how they interact with runners.

Hyperparameter now generates correct dictionaries of hyperparameter permutations.
Reporters now call metrics (instead of metrics calling reporters).
Included unit tests for Hyperparameter and Reporter.

Fix paths in __init__.py
