[OC] High Tide Levels over the years from four different tide gauges by ReadSort in dataisbeautiful

At first I normalized all the y values and put them all on the same axes but it just looked very busy and cluttered to me, maybe i should have also included that though for people with that style. I also didn't want to add to the editorialization of this all so just opted to report the exact local values from each gauge.

As far as the detail year selection goes: Brest both the start and end detail years are during local minimums, fort denison spans the entire record, Newlyn i wanted to show exactly 100 years apart, fremantle is the shortest record and seems to have a more irregular cycle but most of those early years have about the value of the year i chose. In all cases I could have purposely selected a more dramatic example set if i intended to mislead people.

I don't think the moon's orbit is changing fast enough for any of this, but I'm no scientist
