Reason

@aprilnovak reported that she would like the option to force the printing of any TIMED_SECTION. This makes complete sense in the case where you always want to report to the user that something is complete.

Design

Add another option (or another macro) to add this option to TIMED_PRINT

Impact

None - new capability

Please describe the problem you are trying to solve.
The current implementation of the barycentric coordinates are overly complicated and explicitly require the normals of triangles or edges. There are simpler ways to implement this.

Describe the solution you propose.

• Simplify math/barycenter.[ch]pp
• Remove Edge::computeNormal() as it is unnecessary.

**Describe alternativ

I am using SimPEG.Utils.download for gpgLabs. The download messages are distracting in notebooks, so I wanted to suppress them. The option is controlled by "verbose=false", but it does not stop writing "Downloading ... Saved to:.." message.
Can verbose=false swtich kill all the print output?

Looking at the FluidSolver.py, I noticed that a few things are a bit uncommon in the time loop:

It looks like the checkpointing assumes that the solver time step is equal to the coupling time window. More specifically, whenever preCICE does not ask the solv
