function [header_mat,data_mat] = mhdrload(file)
%MHDRLOAD Load data from an ASCII file containing multiple text
% headers throughout the file.
% [header, data] = MHDRLOAD('filename.ext') reads a data file
% called 'filename.ext', which contains a text header. There
% is no default extension; any extensions must be explicitly
% supplied.
%
% The first output, HEADER, is the header information, returned
% as a text array.
% The second output, DATA, is the data matrix. This data matrix
% has the same dimensions as the data in the file, one row per
% line of ASCII data in the file. If the data is not regularly
% spaced (i.e., each line of ASCII data does not contain the
% same number of points), the data is returned as a column
% vector.
%
% Limitations: No lines of the text header can begin with
% a number. The header must come before the data.

% EXAMPLE:
% If example_data.txt is:
% Recorded Data: 12/15/2001
% header 1
% rows = 2 cols = 2
% 12 23
% 34 21
% header 2
% rows = 3 cols = 3
% 19 73 13
% 33 32 47
% 34 12 68
%
% MHDRLOAD returns:
% header(:,:,1) =
%
% Recorded Data: 12/15/2001
% header 1
% rows = 2 cols = 2
%
% header(:,:,2) =
%
% header 2
