Enhancement: Statistics

[stuffi3000]

Hello everyone,

First of all thank you very much for your app. I've been using it for a little while now, and it feels really good and polished. It's also great to see an open source alternative to the big player in the market.

Before switching to RunnerUp, I used FitRunner. A neat feature they had was a small section of the history tab dedicated to providing monthly statistics on all recorder activities. It had a diagram with the amount of kilometers run during the month, as well as a list with the total amount of kilometers, number of trainings, average speed and burned calories.

Would it be possible to implement something similar here in RunnerUp? It would be a great feature to have a look at one's evolution over time.

Thank you very much!
