// ISchemaAttributeType is the base interface for a "type" of attribute, where "type" is defined as
// "something that describes the memory layout, the DB layout, how to convert between them, etc.".
// Most of the low-level work done with attributes, including DB reading/writing, packing/unpacking
// for wire traffic, and other leaf code works exclusively through this interface.
//
// The class hierarchy looks like:
//
//		ISchemaAttributeTypeBase< TAttribInMemoryType >:
//	
//			This describes a specific in-memory format for an attribute, without any association to
//			a particular DB, wire format, etc. We can't template the base class because it's an
//			interface. This implements about half of ISchemaAttributeType and has its own mini
//			interface consisting of ConvertTypedValueToByteStream()	and ConvertByteStreamToTypedValue(),
//			both of which do work on statically-typed values that don't exist at higher levels.
//
//		CSchemaAttributeTypeBase< TAttribSchType, TAttribInMemoryType >:
//
//			This handles the schema-related functions on ISchemaAttributeType. These exist at a lower
//			inheritance level than ISchemaAttributeTypeBase to allow code that needs to work type-safely
//			on attributes in memory, but that doesn't know or need to know anything about databases,
//			to exist. Examples of this include code that calls CEconItem::SetDynamicAttributeValue<T>().
//
//			Individual implementations of custom attribute type start making sense immediately as
//			subclasses of CSchemaAttributeTypeBase, for example CSchemaAttributeType_Default, which
//			implements all of the old, untyped attribute system logic.
//
//		CSchemaAttributeTypeProtobufBase< TAttribSchType, TProtobufValueType >
//
//			An easy way of automating most of the work for making a new attribute type is to have
//			the in-memory format be a protobuf object, allowing reflection, automatic network support,
//			etc.
//
// Creating a new custom protobuf attribute consists of three steps:
//
//		- create a new DB table that will hold your attribute data. This needs an itemid_t-sized item ID
//		  column named "ItemID", an attrib_definition_index_t-sized definition index column named "AttrDefIndex",
//		  and then whatever data you want to store.
//
//		- create a new protobuf message type that will hold your custom attribute contents. This exists
//		  on the client and the GC in the same format.
//
//		- implement a subclass of CSchemaAttributeTypeProtobufBase<>, for example:
//
//				class CSchemaAttributeType_StrangeScore : public CSchemaAttributeTypeProtobufBase< GC_SCH_REFERENCE( CSchItemAttributeStrangeScore ) CAttribute_StrangeScore >
//				{
//					virtual void ConvertEconAttributeValueToSch( itemid_t unItemId, const CEconItemAttributeDefinition *pAttrDef, const union attribute_data_union_t& value, GCSDK::CRecordBase *out_pSchRecord ) const OVERRIDE;
//					virtual void LoadSchToEconAttributeValue( CEconItem *pTargetItem, const CEconItemAttributeDefinition *pAttrDef, const GCSDK::CRecordBase *pSchRecord ) const OVERRIDE;
//				};
//
//		  Implement these two GC-only functions to convert from the in-memory format to the DB format and
//		  vice versa and you're good to go.
//
//		- register the new type in CEconItemSchema::BInitAttributeTypes().
//
// If the attribute type can't be silently converted to an already-existing attribute value type, a few other
// places will also fail to compile -- things like typed iteration, or compile-time type checking.
//
// Functions that start with "Convert" change the format of an attribute value (in a type-safe way wherever
// possible), copying the value from one of the passed-in parameters to the other. Functions that start with
// "Load" do a format conversion, but also add the post-conversion value to the passed-in CEconItem. This
// comes up most often when generating new items, either from the DB (LoadSch), the network (LoadByteSteam),
// or creation of a new item on the GC (LoadOrGenerate).
