Create index

[luizaandrade]

There are a few topics that will be mentioned in different chapters, and indexing them will help us keep track of that as we review the text.

I thought I already had this set up... it was in early drafts of the PDF but it is not there anymore! Anyway the index{} command is used throughout and automatically populates this when it is done correctly.

I found that more people had issues with makeidx package, so someone had written a wrapper for that package called imakeidx that we are now using and works better.

\index{} is creating an extra space in the text. We (i.e myself) should fix that!

[kbjarkefur]

It is not \index{} that create the extra spaces, it is \sidenote{}. But it is not consistently an extra space.

[kbjarkefur]

it is \index{} and \sidenote{} in conjunction, and sometimes new line in text editor. To solve this try the following:

1. Since \index{} does not appear in the text, see if it can be moved so it is one word, or even just a full stop removed from \sidenote{}. Obviously do not move it too far as we do not want the page references on the index page to be imprecise.
2. \index{} should not be on a new row by itself.
3. Make sure that some word or character follows on the same line as \sidenote{}, as in the closing bracket } in \sidenote{} is not the last character on that line in the text editor.
