Replace TealData with teal_data in the docs

[chlebowa]

Closes #231

Modified example apps to use the following pattern:

1. create cdisc_data
2. use within to evaluate code one line at a time
3. set datanames manually (enumerate datasets)
4. set join keys automatically with default_cdisc_join_keys[datanames(data)]
5. assign datasets in global
6. create app
7. run app

Added package prefixes to all teal* package functions.

I'm afraid checks will keep failing because I neglected to put @78_... in my branch name.
