Create a start workout page

[jnair9]

We need to make a tab that allows users to start a workout from their phone.
We need to be able to host these activities:
Run,
Bike,
Hike,

Eventually will push information into Healthstore, but there is another team working on that now so we can wait until they have it implemented:

run: time, pace, distance
hike: elevation, time, distance
bike: time, average mph, elevation
