5.5. The Circle class

Each instance represents a circle with its center at a specific latitude and longitude, to the nearest minute.

.lat: Latitude as a string of four digits, "ddmm".
.lon: Longitude as a string of five digits, "dddmm".
.water: Water-body code: " ", "p", "o", or "e".
.odd: Odd-shape code, " ", "p", or "x".
.cir_name: Full name of the circle, as Unicode.
.regions: An iterator that produces the Region instances for this circle's regions, in standard order as published.
.physios: An iterator that produces the Physio instances for this circle's physiographic strata. If there are two, the first is the major stratum and the second is the minor stratum.
.efforts: An iterator that produces the Effort instances for the circle-years this circle was counted, in chronological order.
.allRegions(): Returns a string of the form “R0[-R1[-R2]]”, where each Ri is one of the region codes for this circle.
.fullName(): This method returns a string of the form “ddmmn dddmmw R0[-R1[-R2]]: cir_name ”. Example: "3843n 08528w IN-KY: Hanover-Madison".
.unicode(): Returns a string like “38°43′N 085°28′W IN-KY: Hanover-Madison”.
