Guidance: Multiple Temporal Coverages

[dvirlar2]

• Add code to reference document
• Code from Erika on how to set multiple temporal coverages when both are a range of dates:

doc$dataset$coverage$temporalCoverage <- list(
  eml$temporalCoverage(rangeOfDates = list(beginDate = list(calendarDate = 2005),
                                           endDate = list(calendarDate = 2010))),
  
  eml$temporalCoverage(rangeOfDates = list(beginDate = list(calendarDate = 2013),
                                           endDate = list(calendarDate = 2019))))

If for some reason a PI wants to show two discrete years, but not month or day, can use the following code and will validate true:

singleTempCov <- list(
  eml$temporalCoverage(singleDateTime = list(calendarDate = 2020)),
  eml$temporalCoverage(singleDateTime = list(calendarDate = 2022))
)

Using the EML::set_coverage() function as described in the Set Multiple Coverages section of the reference manual didn't work as expected, and instead created a validation error. Just requires more input than what's alluded to in the manual, and I'd like it to be more straightforward. Will probably remove.
