MtApi5: Matlab compatibility - SerializableAttribute

[KptKuck]

Matlab can not save .NET data types. At least not at the moment.
The only way is to serialize the data types. Unfortunately, the "SerializableAttribute" is not set for the crucial types.

Would this be possible for all data types that are exported?

Hi.
I think it is possible to add serializable attribute for some types of MtApi or make helper for serialization of the object. I will investigate all possible ways to do this task.
