Producer class to generate (numeric) sequences

A Producer-class to generate a sequence (possibly long) of numbers.

Seq(from = 1L, to=.Machine$integer.max, by = 1L, yieldSize=1L,
    ...)

`from`	A starting value of any type (e.g., `integer`, `numeric` supported by `base::seq`.
`to`	An ending value, typically of the same type as `from`.
`by`	A value, typically of the same class as `from`, indicating the increment between successive numbers in the sequence. `by = 0` can create an infinite stream.
`yieldSize`	A `integer(1)` indicating the length of the output sequence each time `yield()` is invoked.
`...`	Additional arguments passed to `Producer`.

Use Seq to construct instances of this class.

s <- Seq(1, 10, yieldSize=5)
while(length(y <- yield(s)))
    print(y)
