{{alias}}( N, M, initial, si, oi, out, so, oo )
    Factorizes a sequence length into a product of integers.

    Factorization results are stored in the output array sequentially, where
    the first element contains the sequence length N, the second element
    contains the number of factors into which N was decomposed and subsequent
    elements contain the individual integer factors.

    Any remaining array space remains as unused storage.

    Parameters
    ----------
    N: integer
        Length of the sequence.

    M: integer
        Number of trial divisors.

    initial: Collection<number>
        Array of initial trial divisors.

    si: integer
        Stride length for `initial`.

    oi: integer
        Starting index for `initial`.

    out: Collection<number>
        Output array for storing factorization results.

    so: integer
        Stride length for `out`.

    oo: integer
        Starting index for `out`.

    Returns
    -------
    numFactors: integer
        Number of factors into which N was decomposed.

    Examples
    --------
    > var N = 630;
    > var initial = [ 3, 4, 2, 5 ];
    > var factors = [ 0, 0, 0, 0, 0, 0, 0 ];
    > var numFactors = {{alias}}( N, 4, initial, 1, 0, factors, 1, 0 )
    5
    > factors.slice()
    [ 630, 5, 2, 3, 3, 5, 7 ]
