Add section about refactoring.

Refactoring is an essential part of the software development lifecycle, and should thus be given appropriate consideration. I’ve added a section about refactoring, briefly addressing both continuous and planned refactoring.

Most projects/products in Aptoma have done (or will/should do) significant refactoring projects. These have, however, mostly been planned, executed, and evaluated within each team, with little opportunity for getting input from other teams that may have faced similar problems, and with little output in the form of procedures, tools and insight other teams could benefit from.

I believe always trying to involve participants from other projects in planning and evaluation will be beneficial for everyone.
