Book construction

[tschm]

@HarryCampion

Two thoughts you are better qualified to talk about

1. We may not need minibook at all! You know have more professional tools in place. I have created minibook and it served well for a time but we may slicker (and still free) tools

2. Currently book.mk is trying to execute all the jobs it needs to fill the book. We could also have a global variable, e.g. some sort of pages dictionary where the different makefiles write into. The book.mk is then not trying to execute tests etc. It's just displaying whatever is in the pages variables

You must be a mind reader...

Have got something that might work, wip at the moment. Can PR soon.
