Finalized function SEA.m and SEA_CI.m, for Fig. 5

(1) Completed new functions SEA.m and SEA_CI.m, which create a composite
record, and bootstrapped CIs via block resampling, respectively. These
function replace the previous functions "createComposite.m"
"createFullRandComposite.m" and do not depend on the function
"randBlock." The randomization that occurred in randBlock.m now happens
in line 29 of SEA_CI.m, also calling on the randperm function in Matlab.
I compared these two approaches and they produce the same results.
Further, when comparing old figures to new figures there are what need
to be updated:

Fig. 4: Everything is the same, but I noticed that non-high-res fires
(dots) were not present in the C_acc time series plot in the submitted
figures. I resaved this figure at Fig_4_v4_800dpi.m and *.fig in
P:\1_working\Manuscripts\Manuscripts_published\2014_Dunnette_et_al_ChickareeLk\Figures\Fig_4_TimeSeries
THIS FIGURE NEEDS TO BE RESENT TO NEW PHYTOLOGIST.

Fig. 5 -- this figure was same, with the only differences accounted for
by the random block resampling. That is, differences between the current
version at New Phytologist and new figure is the same as what I get if I
make the new figure twice. THIS FIGURE DOES NOT NEED TO BE RESENT TO NEW
PHYTOLOGIST.
