+				This class is used when multiple adjacent blocks are to be manipulated. Because of chunking
+				and multithreading, manipulating single blocks using {{api:cWorld|cWorld:SetBlock}}() is a rather
+				time-consuming operation (locks for exclusive access need to be obtained, chunk lookup is done
+				for each block), so whenever you need to manipulate multiple adjacent blocks, it's better to wrap
+				the operation into a cBlockArea access. cBlockArea is capable of reading / writing across chunk
+				boundaries, has no chunk lookups for get and set operations and is not subject to multithreading
+				locking (because it is not shared among threads).</p>
+				<p>
+				cBlockArea remembers its origin (MinX, MinY, MinZ coords in the Read() call) and therefore supports
+				absolute as well as relative get / set operations. Despite that, the contents of a cBlockArea can
+				be written back into the world at any coords.</p>
+				<p>
+				cBlockArea can hold any combination of the following datatypes:<ul>
+					<li>block types</li>
+					<li>block metas</li>
+					<li>blocklight</li>
+					<li>skylight</li>
+				</ul>
+				Read() and Write() functions have parameters that tell the class which datatypes to read / write.
+				Note that a datatype that has not been read cannot be written (FIXME).</p>
+				<p>
+				Typical usage:<ul>
+					<li>Create cBlockArea object</li>
+					<li>Read an area from the world</li>
+					<li>Modify blocks inside cBlockArea</li>
+					<li>Write the area back to a world</li>
