    getAsOf Get molecule data asOf point in time.
    getSince Get molecule data since point in time.
    getWith Get molecule data with given data set.
    getHistory Get molecule data from history of database.
    save Save molecule with applied data.
    insert Insert multiple rows of data matching a molecule.
    update Update molecule with applied data.
    tx Molecule transaction data (input to `getWith`).
    inspect get Inspect calling get method on molecule.
    inspect operation     Inspect calling save/insert/update method on molecule.

trait insert extends AnyRef

Insert one or more rows of data matching a molecule.

Returns Future with TxReport having info about the result of the insert transaction.

Data matching the types of the molecule can be inserted either as individual args or an Iterable (List, Set etc) of tuples:

val singleInsertFuture: Future[TxReport] = Person.name.age.insert("Ann", 28)

// Insert multiple rows of data. Accepts Iterable[Tpl]
val multipleInsertFuture: Future[TxReport] = Person.name.age insert List(
  ("Ben", 42),
  ("Liz", 37)
)

for {
  // Insert single row of data with individual args
  _ <- Person.name.age.insert("Ann", 28)

  // Insert multiple rows of data. Accepts Iterable[Tpl]
  _ <- Person.name.age insert List(
    ("Ben", 42),
    ("Liz", 37)
  )
  _ <- Person.name.age.get.map(_ ==> List(
    ("Ann", 28),
    ("Ben", 42),
    ("Liz", 37)
  ))
} yield ()

The insert operation is asynchronous and non-blocking. Internally calls Datomic's asynchronous API.
