Tutorial revision + Spanish translation

Hello folks, we've been thinking that it would be a good idea to have an Spanish version of the tutorial. But before starting the translation efforts we were wondering if we want to do a tutorial revision.

The reason I asked this is because I noticed that the tutorial is designed to be delivered by someone who fills in the gaps as the tutorial goes live or via video, but if someone is following the notebooks by themselves, there are certain parts where the material doesn't feel self contained. We also have examples that are not working (For example, the recently issue report #213 )
What do we think about this, what is the best way to update the tutorial and what do we want in it?

Regarding the Spanish translation I'll be happy to take the lead on it, I'd like to know if there are more people in the dask community that speaks Spanish and that could potentially help.

首先查看教程 notebooks 以及 issue #213 中引用的损坏示例。确定哪些材料不具备自包含性，以及哪些示例需要修正，然后在开始西班牙语翻译之前记录已达成一致的修订范围。当修订计划和翻译方案确定后，即视为完成。
