Flatten a parse table

Description

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.

Usage

flatten_pd(pd_nested, token, child_token = token, left = TRUE)

Arguments

`pd_nested`	A nested parse table.
`token`	A character vector with tokens of which at least one has to occur in `pd_nested` in order to flatten it.
`child_token`	A character vector of tokens of which at least one has to occur in the child in order to flatten the parse table.
`left`	Flag that indicates whether the parse table should be flattened from left or from right.
