trait median extends AnyRef
Median of attribute values.
Median of attribute values.

Apply median keyword to attribute to return median of attribute values of entities matching the molecule.
```
Match.sKeywords.insert(1, 2, 4)
Match.score(median).get.head === 2
```
OBS: When it comes to an even number of values, Datomic has a special implementation of median that is different from the one described on the Wiki entry on the median function.

Datomic calculates the median of even number of values as the average of the two middle numbers rounded down to nearest whole number
```
Match.sKeywords.insert(1, 2, 3, 4)
Match.score(median).get.head === 2 // (2 + 3) / 2 = 2.5 rounded down to 2
```
With decimal numbers this can go wrong:
```
Match.sKeywords.insert(1.0, 2.5, 2.5, 3.0)
Match.score(median).get.head === 2 // (2.5 + 2.5) / 2 = 2.5 rounded down to 2 (This is wrong and bug report has been filed)

def inspectRetract(eids: Iterable[Long], txMetaDataMolecules: Molecule*)(implicit conn: Conn): Unit

Inspect retracting multiple entities with optional transaction meta data.

Inspect retracting multiple entities with optional transaction meta data.

Without affecting the database, a multiple entity retract action can be inspected by calling the inspectRetract method.

Here we inspect a possible retraction of two comment entities with transaction meta data asserting that the retraction was done by Ben Goodman:

inspectRetract(Seq(commentEid1, commentEid2), MetaData.user("Ben Goodman"))

This will print inspecting info about the retraction to output (without affecting the database):

def retract(eids: Iterable[Long], txMetaDataMolecules: Molecule*)(implicit conn: Conn): TxReport
Retract multiple entities with optional transaction meta data.
Retract multiple entities with optional transaction meta data.

0 or more transaction meta data molecules can be asserted together with a retraction of entities.

Here we retract two comment entities with transaction meta data asserting that the retraction was done by Ben Goodman:
```
retract(Seq(commentEid1, commentEid2), MetaData.user("Ben Goodman"))
```
We can then later see what comments Ben Goodman retracted (op_(false)):
```
Comment.e.text.op_(false).Tx(MetaData.user_("Ben Goodman")).getHistory === List(
  (commentEid1, "I like this"),
  (commentEid2, "I hate this")

Transact tx function invocation

Macro that takes a tx function invocation itself as its argument.
Transact tx function invocation

Macro that takes a tx function invocation itself as its argument. The tx function is analyzed by the macro and the necessary transaction preparations done at compile time.

At runtime, the returned statements from the tx function is transacted as one atomic transaction.
```
val txReport = transact(transfer(fromAccount, toAccount, 20))

Transaction meta data molecules can be added
```
// Add tx meta data that John did the transfer and that it is a scheduled transfer
