Design and implement serialization of nfEngine's object

[lookeypl]

Serialization routines must cover:

• scene (with segments)
• entities
• components
• resources

Serialization should be done in binary format.

There should be introduced a new entity property - "static". A static entity can not be modified during a gameplay. Only non-static entities should be included in a game savestate. (To be discussed)

Split this task into subtasks if needed.
