Added BigDecimalSamples project.
Due to the fact that Cassandra uses java's 'BigDecimal' for representing 'decimal' data type and C# doesn't provide it (there is 'decimal' data type in C#, but it is confined only to 16 bytes http://msdn.microsoft.com/en-us/library/364x0z75.aspx), 'ITypeAdapter' interface has been exposed, so user can create own BigDecimal type adapter.
This sample shows how to create one. It uses IKVM.NET libraries. To change type adapter that handles decimal values, only one line of code is needed:
  TypeAdapters.DecimalTypeAdapter = new MyDecimalTypeAdapter();
Where 'MyDecimalTypeAdapter' class must implement 'ITypeAdapter' interface.
