/**
* An identifier used to access a market quote.
* <p>
* A quote ID identifies a piece of data in an external data provider.
* <p>
* Where possible, applications should use higher level IDs, instead of this class.
* Higher level market data keys allow the system to associate the market data with metadata when
* applying scenario definitions. If quote IDs are used directly, the system has no way to
* perturb the market data using higher level rules that rely on metadata.
* <p>
* The {@link StandardId} in a quote ID is typically the ID from an underlying data provider (e.g.
* Bloomberg or Reuters). However the field name is a generic name which is mapped to the field name
* in the underlying provider by the market data system.
* <p>
* The reason for this difference is the different sources of the ID and field name data. The ID is typically
* taken from an object which is provided to any calculations, for example a security linked to the
* trade. The calculation rarely has to make up an ID for an object it doesn't have access to.
* <p>
* In contrast, calculations will often have to reference field names that aren't part their arguments. For
* example, if a calculation requires the last closing price of a security, it could take the ID from
* the security, but it needs a way to specify the field name containing the last closing price.
* <p>
* If the field name were specific to the market data provider, the calculation would have to be aware
* of the source of its market data. However, if it uses a generic field name from {@code FieldNames}
* the market data source can change without affecting the calculation.
