Version comparison

[ErdaradunGaztea]

Use case

Comparing two version codes:

code_1 <- "1.5.10-11b"
code_2 <- "1.5.1"
ver_older_than(code_1, code_2)
# FALSE
ver_later_than(code_1, code_2)
# TRUE

Proposed name

Preferably something with older and later to be consistent with ver_oldest() and ver_latest(). A ver_ prefix would also be preferred. On the other hand, the names should not be too similar to the aforementioned functions. ver_is_older() would work well, but is_ prefix is usually connected with single argument check.
Thus, the current best is ver_older_than(). An alternative would be to have ver_compare() that returns -1, 0 and 1, but I don't like the low-level feel of this; in any case I'd want functions that return a boolean too.
