plotSizeCompsComparisons: Function to plot size comps comparisons by year
In wStockhausen/rTCSAM2013: Functions to run and plot output from TCSAM2013 models.

This function compares observed and predicted size comps by year.

1 2	plotSizeCompsComparisons(data.o, data.p, nr = 4, nc = 4, nplots = nr * nc, new = TRUE, len = TRUE, maxy = NULL, yearlb = NULL)

`data.o`	- observed size comps
`data.p`	- predicted size comps
`nr`	- number of rows per page
`nc`	- number of columns per page
`nplots`	- total number of plots
`new`	- flag to set and return graphics parameters
`len`	- flag indicating length comps
`maxy`	- max y value to plot
`yearlb`	- year labels, one per plot
