A fairly tidy time-series quantile plot

```
plotquant(
x,
p = c(0.05, 0.25, 0.75, 0.95),
yrs,
qcol,
lcol,
addline = T,
ablines = NA
)
```

- x
Matrix. A time series quantity

`[simulation, year]`

- p
Numeric vector. The percentiles that are plotted (LB2,LB1,UB1,UB2). LB2 and UB2 are the outer percentiles, LB1 and UB1 are the inner percentiles.

- yrs
Numeric vector. The years corresponding to the indexing of x

- qcol
Character, color. The color of the inner percentile range

- lcol
Character, color. The color of the outer percentile range.

- addline
Logical. Should two individual simulations be added to the percentile plots?

- ablines
Numeric vector. Horizontal lines to be added to the plot.
