Create PubMed query strings for each DOI batch

1	create_query_strings(dois, terms = NULL)

`dois`	List or character vector of DOIs. For multiple DOI batches, use a list of character vectors. For a single doi batch, use a character vector or list (of length 1) of character vectors. Generally the output of `batch_dois`
`term`	OPTIONAL. Character string of additional terms to append to each query string. Include appropriate booleans. See PubMed Help for available tags.

NOTE: I understand "query string" and "search string" to be synonymous. I use "query string" for internal consistency.

Character vector of length number of batches (length dois if dois is a list, else 1)

# With a single batch of DOIs as a character vector
my_dois <- c("10.3389/fpsyt.2018.00207", "10.1186/s40779-018-0166-5", "10.1186/s12959-018-0173-5", "10.1103/PhysRevD.97.096016", "10.1038/d41586-018-05113-0")

create_query_strings(my_dois)
create_query_strings(my_dois, term  = 'AND "clinical trial"[Publication Type]')

# With multiple batches of DOIs as a list of character vectors
my_dois_list <- list(c("10.3389/fpsyt.2018.00207", "10.1186/s40779-018-0166-5", "10.1186/s12959-018-0173-5"), c("10.1103/PhysRevD.97.096016", "10.1038/d41586-018-05113-0"))
