+		The MemoryMap object describes a system-level memory map into which a BinaryView is loaded. Each BinaryView
+		exposes its portion of the MemoryMap through the Segments defined within that view.
+
+		A MemoryMap can contain multiple, arbitrarily overlapping memory regions. When modified, address space
+		segmentation is automatically managed. If multiple regions overlap, the most recently added region takes
+		precedence by default.
+
+		All MemoryMap APIs support undo and redo operations. During BinaryView::Init, these APIs should be used conditionally:
+		* Initial load: Use the MemoryMap APIs to define the memory regions that compose the system.
+		* Database load: Do not use the MemoryMap APIs, as the regions are already persisted and will be restored automatically.
+
+		This conditional usage prevents redundant operations and ensures database consistency. Using these APIs when loading
+		from a database will also mark the analysis as modified, which is undesirable.
