You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: BrainSurfacePF.m
    path of file: ./repos/BRAPH-2/braph2/src/atlas
    
    the code of the file until where you have to start completion: classdef BrainSurfacePF < PanelFig
	%BrainSurfacePF is a panel figure that manages the plot of a brain surfce.
	% It is a subclass of <a href="matlab:help PanelFig">PanelFig</a>.
	%
	% A Panel Figure for Brain Surface (BrainSurfacePF) manages the plot of the 
	%  brain surface choosen by the user. 
	% BrainSurfacePF provides the common methods needed to manage the plot of 
	%  the surface. In particular, the user can change lighting, material, 
	%  camlight, shadning, colormap, facecolor, brain color, face color, 
	%  edge color, and background color. 
	% A collection of brain surfaces in NV format can be found in the folder 
	%  ./braph2/brainsurfs/.
	%
	% The list of BrainSurfacePF properties is:
	%  <strong>1</strong> <strong>ELCLASS</strong> 	ELCLASS (constant, string) is the class of the panel figure for brain surface.

function prop_category = getPropCategory(pointer)
			%GETPROPCATEGORY returns the category of a property.
			%
			% CATEGORY = Element.GETPROPCATEGORY(PROP) returns the category of the
			%  property PROP.
			%
			% CATEGORY = Element.GETPROPCATEGORY(TAG) returns the category of the
			%  property with tag TAG.
			%
			% Alternative forms to call this method are (POINTER = PROP or TAG):
			%  CATEGORY = PF.GETPROPCATEGORY(POINTER) returns category of POINTER of PF.
			%  CATEGORY = Element.GETPROPCATEGORY(BrainSurfacePF, POINTER) returns category of POINTER of BrainSurfacePF.
			%  CATEGORY = PF.GETPROPCATEGORY(BrainSurfacePF, POINTER) returns category of POINTER of BrainSurfacePF.
			%
			% Note that the Element.GETPROPCATEGORY(PF) and Element.GETPROPCATEGORY('BrainSurfacePF')
			%  are less computationally efficient.

			% See also Category, getPropProp, getPropTag, getPropSettings,
