Design error handling in a better way

[gdiazlo]

We need to design an error handling mechanism that allows us to produce a more robust program. Take a look at https://commandcenter.blogspot.com.es/2017/12/error-handling-in-upspin.html for inspiration.

I'm researching how other projects handle errors and cherry-picking ideas which may apply to our use case.
Currently I'm working on my fork doing some tests and trying to figure out where we need to improve our error handling at this moment.

After discussing this matter with @gdiazlo @panchoh @aalda and @iknite, we decided to put this on hold until we have more mature version of our history and hyper tree implementations.
At this point when we discover some functionality that is difficult to debug we should at least include a good enough error traces.
