CovariateData is an S4 class that inherits from Andromeda. It contains
information on covariates, which can be either captured on a per-person basis, or aggregated across
the cohort(s).
By default covariates refer to a specific time period, with for example different covariate IDs for
whether a diagnosis code was observed in the year before and month before index date. However, a
CovariateData can also be temporal, meaning that next to a covariate ID there is also a time ID,
which identifies the (user specified) time window the covariate was captured.
A CovariateData object is typically created using getDbCovariateData, can only be saved using
saveCovariateData, and loaded using loadCovariateData.
