Detailed Description

Identifies fields.

Fields are necessary to tag data in signed transactions so that the binary format of the transaction can be canonicalized. All SFields are created at compile time.

Each SField, once constructed, lives until program termination, and there is only one instance per fieldType/fieldValue pair which serves the entire application.
