Median of attribute values.

Apply median keyword to attribute to return median of attribute values of entities matching the molecule.
```
Match.score.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.score.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.score.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 debugRetract(eids: Iterable[Long], txMetaDataMolecules: MoleculeBase*)(implicit conn: Conn): Unit

Debug retracting multiple entities with optional transaction meta data.

Debug retracting multiple entities with optional transaction meta data.

Without affecting the database, a multiple entity retract action can be debugged by adding a 'D' (for 'Debug') to the retract method.

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

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

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

def recreateDbFrom(schema: SchemaTransaction, identifier: String = "", protocol: String = "mem"): Conn
Deletes existing database (!) and creates a new empty db with schema from Schema Transaction file.
Deletes existing database (!) and creates a new empty db with schema from Schema Transaction file.

A typical development cycle in the initial stages of creating the db schema:
1. Edit schema definition file
2. sbt compile to update boilerplate code in generated jars
3. Obtain a fresh connection to new empty db with updated schema:
  implicit val conn = recreateDbFrom(YourDomainSchema)
schema
Auto-generated YourDomainSchema Transaction object
(in package yourdomain.schema of generated source jar)
identifier
Optional String identifier to name database (default empty string creates a randomUUID)
protocol
Datomic protocol. Defaults to "mem" for in-memory database.
returns
Conn
Definition Classes
Datomic
def recreateDbFromRaw(schemaData: List[_], identifier: String = "", protocol: String = "mem"): Conn
Deletes existing database (!) and creates a new empty db with schema from schema data structure.
Deletes existing database (!) and creates a new empty db with schema from schema data structure.

Schema data structure is a java List of Map's of key/value pairs defining the schema.

Can be an EDN file like the mbrainz example.
schemaData
java.util.List of java.util.Maps of key/values defining a Datomic schema
identifier
Optional String identifier to name database (default empty string creates a randomUUID)
protocol
Datomic protocol. Defaults to "mem" for in-memory database.

def retract(eids: Iterable[Long], txMetaDataMolecules: MoleculeBase*)(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")
)
```
eids
Iterable of entity ids of type Long
txMetaDataMolecules
Zero or more transaction meta data molecules
conn
Implicit Conn value in scope
returns

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
transact(
  transfer(fromAccount, toAccount, 20),
  Person.name("John"),
  UseCase.name("Scheduled transfer"))

// Query multiple Tx meta data molecules
