Change markers to types

[Konard]

Meaning root should be named just Type or RootType.

Data.Doublets.Json/csharp/Platform.Data.Doublets.Json/DefaultJsonStorage.cs

Lines 280 to 281 in eac0583

	var markerIndex = One;
	MeaningRoot = links.GetOrCreate(markerIndex, markerIndex);

Each marker is just type "inherited" from root type. So, marker links should be like this: (Object: Type -> Object)

Data.Doublets.Json/csharp/Platform.Data.Doublets.Json/DefaultJsonStorage.cs

Lines 284 to 296 in eac0583

	DocumentMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	ObjectMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	MemberMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	ValueMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	StringMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	EmptyStringMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	NumberMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	NegativeNumberMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	ArrayMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	EmptyArrayMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	TrueMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	FalseMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));
	NullMarker = links.GetOrCreate(MeaningRoot, Arithmetic.Increment(ref markerIndex));

Each marker can be named just Object or ObjectType instead of "marker".

The basic type system is like this:

Type -> Type
Type -> Value

So everything that comes after Type is Type or Value. Meaning, we can have infinite depth hierarchy of types. The special case of type is a concrete value (constant of some type).

For example, we can have:

(Array: Type -> Array)
(EmptyArray: Array -> EmptyArray)

Meaning that Array is type. And EmptyArray is concrete value (constant) of type Array.

Each value/constant is still type. Each type can be used as a standalone constant.
