instantiateCohortSet: Instantiate a set of cohorts
In anthonysena/CohortGenerator: Used to generate OHDSI cohorts

This function instantiates a set of cohorts in the cohort table and where specified the inclusion rule statistics are computed and stored in the inclusionStatisticsFolder.

instantiateCohortSet(
  connectionDetails = NULL,
  connection = NULL,
  numThreads = 1,
  cdmDatabaseSchema,
  tempEmulationSchema = NULL,
  cohortDatabaseSchema = cdmDatabaseSchema,
  cohortTable = "cohort",
  cohortSet = NULL,
  inclusionStatisticsFolder = NULL,
  createCohortTable = FALSE,
  incremental = FALSE,
  incrementalFolder = NULL
)

`connectionDetails`	An object of type `connectionDetails` as created using the `createConnectionDetails` function in the DatabaseConnector package. Can be left NULL if `connection` is provided.
`connection`	An object of type `connection` as created using the `connect` function in the DatabaseConnector package. Can be left NULL if `connectionDetails` is provided, in which case a new connection will be opened at the start of the function, and closed when the function finishes.
`numThreads`	Specify the number of threads for cohort generation. Currently this only supports single threaded operations.
`cdmDatabaseSchema`	Schema name where your patient-level data in OMOP CDM format resides. Note that for SQL Server, this should include both the database and schema name, for example 'cdm_data.dbo'.
`tempEmulationSchema`	Some database platforms like Oracle and Impala do not truly support temp tables. To emulate temp tables, provide a schema with write privileges where temp tables can be created.
`cohortDatabaseSchema`	Schema name where your cohort table resides. Note that for SQL Server, this should include both the database and schema name, for example 'scratch.dbo'.
`cohortTable`	Name of the cohort table.
`cohortSet`	The `cohortSet` argument must be a data frame with the following columns: cohortId The unique integer identifier of the cohort cohortFullName The cohort's full name sql The OHDSI-SQL used to instantiate the cohort json The json column must represent a Circe cohort definition. This field is only required when you would like to generate a cohort that includes inclusion statistics since the names of the inclusion rules are parsed from this JSON property.
`inclusionStatisticsFolder`	The folder where the inclusion rule statistics are stored. Can be left NULL if you do not wish to export the inclusion rule statistics
`createCohortTable`	Create the cohort table? If `incremental = TRUE` and the table already exists this will be skipped.
`incremental`	Create only cohorts that haven't been created before?
`incrementalFolder`	If `incremental = TRUE`, specify a folder where records are kept of which definition has been executed.
