init_int64_2D Subroutine

private pure subroutine init_int64_2D(this, rows, grow_factor, start_size)

@brief Set up the re-sizeable array (buffer) with a given start size and grow_factor.

@details Has to be called before first use and can be called any time.

@param[in] rows Number of rows in the first dimension. @param[in] start_size Initial size of the buffer along the last dimension. @param[in] grow_factor Factor about which to grow the buffer along the last dimension, if the capacity is not sufficient.
