-function  [ labels , node_sizes, cases, data] = readInputData( dfile , nnodes )

-	%  readColData  reads data from a file containing data in columns

-	%               that have text titles, and possibly other header text

-	%   

-	%  Input:

-	%     dfile  = name of the file containing the data.(required)

-	%     nnodes  = number of columns in the data file.  (required)

-    %

-    %   Function assumes the following format for the input file:

-    %       1) First line has labels for each of the nodes.  There cannot

-    %              be spaces in any node label.

-    %       2) The next line is the "node_sizes" of the nodes.  If the 

-    %           nodes are discrete, this number will be equal to the number

-    %           of states.  If the nodes are continuous, they should be 

-    %           equal to 1.  The function assumes that any nodes with

-    %           node_size = 1 is continuous.

-    %       3) The rest of the file is numeric data.  The data in the input

-    %               data has the number of columns equal to the number of 

-    %               nodes in the network and the number of rows equal to

-    %               the number of samples.

-    %

-    %

-	%  Output:

-	%     labels = cell array with node (column) labels.

-    %     node_sizes  =  vector with the size of each node

-    %     cases = cell array with the data.  The cases array is transposed

-    %       in comparison with the input data to agree with the format of

-    %       cell data used in BNT.

-    % readInputData is called by readInput.m
