	description: "[
		Encapsulates a transaction in the space. All space operations require a transaction argument.

		There are 2 types of transactions (that correspond to the types of EGS_TRANSACTION_MANAGER
		  - Local Transaction - for operations over a single space instance 
		  - Distributed %Transaction - for operations that span over multiple spaces

		A transaction can be obtained in one of the following ways:
		  - EGS_SPACE_PROXY.create_local_transaction - Local transaction only
		  - EGS_TRANSACTION_MANAGER.create_transaction - Can be Local or Distributed transaction 
		    based on the Transaction Manager type

		Once a transaction is created it can be used with any of the space operations until it is 
		either committed or aborted.

		@note All space operations can also accept Void Transaction meaning no transaction is used.

		@note Some space operations accept isolation level flags (EGS_READ_MODIFIERS) that together with 
		transactions control locking and blocking of objects in the space.

		@see EGS_TRANSACTION_MANAGER, EGS_SPACE_PROXY, EGS_READ_MODIFIERS
