function plotseiswell(wellfile,seisfile)

% function plotseiswell(wellfile,seisfile)
%     This function is the workhorse of seis2well.
%     The two input filenames are the output
%       from readwells (x,y,wellname stuff)
%       and from extract_raster (x,y,trno, t1,t2...)
%     These files are ascii files which can be edited.
%     This function reads the files, makes local
%       coordinates, makes well and seisobjects
%       as specified by G. Margraves architecture,
%       plots the lines and wells 
%     Note, the wells are one object, and each of
%       the lines are one object.  The lines are
%       combined into one container object, and
%       then the wells and seis are combined into
%       a master container object, which is assigned
%       a handle.

disp('beginning to read the wellfile');
[x,y,name]=readwellfile(wellfile);

% The global coordinates are in x and y.

%
% MAKE LOCAL COORDINATES
%
% xr and yr contain local well coordinates. 
% xtrr and ytrr contain local trace coordinates. 
% xr=(x-min(x))/1000. etc.
