Added a few words about compiling Iocaine, added a docker example with a
TOML configuration file (vs the existing environment variable-based
example), and collected a mistake describing the shape of
`IOCAINE__SOURCES__MARKOV`.
These together should largely address #2.

This rebuilds the templating so that the *content* is no longer
pre-generated, only the parameters. It is up to the template (and some
newly implemented helper functions) to construct the output from those.
