bindCache(): web API

1. Design a function to get what people have been working on lately.

library(purrr)

latest_events <- function(username) {
  json <- gh::gh("/users/{username}/events/public", username = username)
  tibble::tibble(
    repo = json %>% map_chr(c("repo", "name")),
    type = json %>% map_chr("type"),
  )
}
