@function [dataout]=merge_files(datain1,datain2)

%[dataout]=merge_files(datain1,datain2)
%
%Function to merge multiple DSI variables into a single DSI variable.
%
%INPUT
%DSI variables in order that they should be merged.  Record structure in
%each varible will be preserved and total number of records in the new
%variable will be the sum of records in all specified input files.
%
%OUTPUT
%dataout - DSI variable that is the result of merging all specified input
%	variables
