UPDATED: Sept. 11th. Saturday.

• Updated wave class to accommodate N, (N \in Non-negative integers) from markers,
• The Global reference block programmatically initiates and adds/deletes viz. blocks based on the number of markers (0 to
  N) defined by the user,
  Here are the steps to enable and define visualization blocks,

1. Define an array with the first column defining the X coordinates, and the second column defining the corresponding Y coordinates. The User should define waves.markLoc = []. If no array is defined, there would be no markers and vice versa,
2. Define marker style by defining waves.markStyle = []; % 1: Sphere, 2: Cube, 3: Frame.
3. Define marker size in pixels by defining waves.markSize = []; % Marker Size in Pixels

Here is an example. In this example a mesh of points is described using the meshgrid command and then making it an array of X and Y coordinates using reshape().
.. Note: The user only needs to initiate the visualization and define an array of visualization blocks.

examples:

1. A simple example with markers in a diagonal layout
   X = 2*[1;2;3;4;5];
   Y = 2*[1;2;3;4;5];
   waves.markLoc = [X,Y];
   waves.markStyle = 2; % 1: Sphere, 2: Cube, 3: Frame.
   waves.markSize = 15; % Marker Size in Pixels

2. An example with a square mesh of visualization blocks:

mrk = 10;
dmrk = 5;
[X,Y] = meshgrid(-mrk:dmrk:mrk,-mrk:dmrk:mrk);
waves.markLoc = [reshape(X,[],1),reshape(Y,[],1)]; % Marker Locations [X,Y]
clear('mrk','dmrk','X','Y')

waves.markStyle = 3; % 1: Sphere, 2: Cube, 3: Frame.
waves.markSize = 20; % Marker Size in Pixels
