Fix typo.
Add endDateMillis and startDateMillis to range/interval response, to
make it easy for clients to turn the values into date objects.
Register binders to parse LocalDate and DateTime request parameters.
Remove dependency on central.web package, to make bundle more easily deployed.
Fix misspelling of "celsius" as "celcius" in weather and day datums. Leave getters for misspelling so existing web service clients don't break.
Add @JsonIgnore for misspelled "Celcius" properties, so not included in web service API responses.
Leave date binder configuration in concrete classes, as their patterns might vary.
