/**
* ## Reference Calculation
*
* ### 1. Intro
*
* Reference Calculation based on configuration in each attribute, `serviceReference` field.
*
* ### 2. Dao Mode
*
* Here are three dao mode in MetaReference
*
* 1. Dynamic Dao: {@link HDao}, based on `M_MODEL` definition.
* 2. Static Dao: directly mapped to single table.
* 3. Static Dao with Join: mapped to more than on table.
*
* ### 3. Dao Map
*
* Here are following hash map rules to store component references:
*
* 1. Each `key = value` pair refer to `source = {@link RQuote}`.
* 2. `references` stored `source = RQuote` hash map.
* 3. For 「Static」 mode, each {@link RQuote} stored `condition = RDao`.
*
* The example is as following:
*
* ```
* //
* source1: res.employee ( type = io.vertx.up.experiment.reference.RQuote )
* conditionA = RDao |-- ( type = io.vertx.up.experiment.reference.RDao )
* -- supportAName
* -- supportGroup
* -- supportSection
* conditionB = RDao |-- ( type = io.vertx.up.experiment.reference.RDao )
* -- supportBName
* source2: rl.device.relation ( type = io.vertx.up.experiment.reference.RQuote )
* conditionC = AoDao |-- ( type = io.vertx.up.experiment.reference.RDao )
* -- up
* conditionD = AoDao |-- ( type = io.vertx.up.experiment.reference.RDao )
* -- down
* //
* ```
*
* > `conditionX` could be calculated by `key` ( include "" default value )
*
* ### 4. Result Map
*
* Here are following hash map rules to store component result:
*
* 1. Each `key = value` pair refer to `field = {@link RResult}`.
* 2. `result` stored `source = RResult` hash map and refer to `RDao`.
*
* The example is as following:
*
* ```
* //
* ( type = io.vertx.up.experiment.reference.RResult )
* supportAName = RResult
* supportBName = RResult
* supportGroup = RResult
* supportSection = RResult
* up = RResult
* down = RResult
* //
* ```
