Flatten a parse table
Flattens a parse table if certain tokens occur in this table or its child,
either flattening from left or from right. If one of token is present in
pd_nested and one of child_token is present in one of the children next
to token in pd_nested, the nested parse table is flattened. Otherwise, it
is returned unmodified.
flatten_pd(pd_nested, token, child_token = token, left = TRUE)
