C# Класс VoltDB.Data.Client.VoltDecimal

Define the Volt-specific decimal(38,12) structure over the standard Java-like implementation of BigDecimal. Full operator support provided. Some methods removed, consistent with the fixed-sclae behavior.

All conversion and mathematical operations maintain the fixed scale at 12 digits -> some operations might lose precision or throw overflow exceptions.
