qx_to_lx

The survival curve is calculated as the cumulative product of the conditional survival probabilities, which are the complement of conditional death probabilities, <code>qx</code>, except we take care to start with a clean 1. This function no radix option. <code>lx</code> with a radix of 1 can be interpreted as the probability of surviving from birth to age <code>x</code>.
