[feature] : Remove "grain junctions" from grain_statistics.csv

[SylviaWhittle]

Is your feature request related to a problem?

"grain_junctions" is calculated as the number of pixels that are designated as junctions (number of pixels that have > 2 neighbours).

Users are mistakenly thinking this means number of DNA crossings. This is bad and not correct. Users don't need to know the number of pixels that are designated as junctions, I don't see a use for it.

Describe the solution you would like.

Remove it from the grain_statistics.csv file.

Describe the alternatives you have considered.

Sounds like a small change, two options...

1. Wait for me to complete refactoring (very close now as I've found why there was a difference, see here) and then make the change.
2. I remove it in my current work.

A third option might be to leave it in and make the documentation clearer but if no one uses it then I'd agree with removing it.

Looking at this I have added grain_junctions as an attribute to the DisorderedTrace class. Should it be removed as an attribute there too or is it something some people (developers) might need or be interested in and should therefore remain in place?
