%IMPORTFILE Import data from a spreadsheet
%   [subject,week,file] = IMPORTFILE(FILE) reads data from the first
%   worksheet in the Microsoft Excel spreadsheet file named FILE and
%   returns the data as column vectors.
%
%   [subject,week,file] = IMPORTFILE(FILE,SHEET) reads from the specified
%   worksheet.
%
%   [subject,week,file] = IMPORTFILE(FILE,SHEET,STARTROW,ENDROW) reads from
%   the specified worksheet for the specified row interval(s). Specify
%   STARTROW and ENDROW as a pair of scalars or vectors of matching size
%   for dis-contiguous row intervals. To read to the end of the file
%   specify an ENDROW of inf.%
% Example:
%   [subject,week,file] = importfile('index.xlsx','Sheet1',2,22);
