## Visit'em all

### Description

Apply a list of functions to each level in a nested parse table. `pre_visit()` applies `funs` before it proceeds to the children, (that is, starts from the outermost level of nesting progressing to the innermost level), `post_visit()` proceeds to its children before applying the functions (meaning it first applies the functions to the innermost level of nesting first and then going outwards).

### Usage

    pre_visit(pd_nested, funs)

    post_visit(pd_nested, funs)

### Arguments

`pd_nested` | A nested parse table.
`funs` | A list of transformer functions.
