Discussion: Rearrange content across modules for balance and flow

[bencomp]

This issue is a follow-up to #90, of which the other points made have been addressed.

The submitter (not the issue opener) said:

Personally, I think the class may be reorganized. Currently, there are a lot of information in "working with OpenRefine" section. For example, Transforming data using GREL could be moved to the "examine numbers" section. That part is also doing data transformation. I would start by using the common transfer, then introducing GREL. GREL might be a little bit tricky for beginners, so I would not introduce in the earlier part of the class.

I would like to try to rearrange various sections within their module or across modules. Other issues mention the order of content too, like #84 and #95.
This issue will be updated with more specific ideas.

My suggestions (totally inspired by the mentioned issues):

• remove the "Getting help" from the introduction
• update the resources 'episode' with current resources
• move "Create a project" from episode 2 to episode 1 (so that the objective to understand the user interface is almost met)
• include the column ordering menu at the start of episode 2 (see Introduce menu for column reordering #83)
• in episode 2, start with "Trim (...) whitespace" as the first demonstration of transforming data, after showing the variation using a text facet. Clustering is very cool, but can wait until later.
• Demonstrate undo and redo following the first actions
• somehow I would like to put facets and filters in the same episode. They provide similar functionality.
• Maybe first cover text filtering and sorting as basic functionality, before showing how facets are more powerful?
