Module03: Materials for dplyr lesson

[tavareshugo]

List of things that we think should be covered in the dplyr lesson:

• filter
• select
• mutate
• Introduce pipes %>%
• "split-and-apply" summaries: data %>% group_by %>% summarise

Perhaps it's also good if we relate this to the previous ggplot lesson

A first draft of the module 03 is done. Please have a look and let me know if anything needs to be changed!
