The add_block method looks for the `block` attribute and appends
it to the running blocks.
Lines represent each attribute to dicover within the _Start_ and _stop_
content of a block. Each `PlogLine` extracts an explicitly designed
value, adding it to the 'lines' of a block.
A block returns the line value as a dictionary attribute in `Plug.data_block`.
