sas_extract_let_strings

<p>is a vector of character strings, typically taken from something
like <code>readLines(some_sas_file_path)</code></p>

<p>Finds all the LET statements in some SAS code and writes them to an R list.
The list item name is the SAS variable name, and each list item is a
character vector of the contents. This is specifically for string
assignments, but probably easy to adapter to numbers if ever needed.</p>
