contact mechanics units #15

When calculating base don "flat punch" geometry, the x-axis units are still in units of pressure instead of load. The previous version of the webapp used units of N/E while the current uses p/E of both periodic and flat punch.

The units of pressure are also shown if the user mouses over a data point. Units of pressure are also used in the y-axis of the load-vs. displacement.

I am not sure if this is a bug or just a new calculation that has everything based on pressure rather than load.

@pastewka , @AntoineSIMTEK , can we discuss this tomorrow?

E is not a load unit. I guess it is implicitely E µm^2 , if the lateral unit of the surface is µm.
