Removing an agent or an informant's association to a table-reading
function can be done with remove_read_fn(). This may be good idea in an
interactive session when instead relying on the direct association of a data
table (settable in create_agent() and create_informant()'s tbl argument
or with set_tbl()). The table-reading function can be set again with
set_read_fn().
remove_read_fn(x)An agent object of class ptblank_agent, or, an informant of
class ptblank_informant.
