% DESCRIPTION
%
% Create base window for current GUI phase.
%
% DESIGN NOTES
%
% This function switches on the value of guiPhase:
%   0 = Startup configuration window - Y/N query for runtime graphical output
%   1 = Runtime output window - either graphical plots or text status
%   2 = Termination window with OK button
%
% VARIABLES
%
% INPUTS
%   guiPhase   -   Current phase of GUI operation (start, runtime, termination)
%
% OUTPUTS
%   Creates output window with text and axes, ready for data.
%
% INTERNALS
%   NameStr    -   Output window title string
%   FileStr    -   Output window filename string
%   StatStr    -   Output window status string - frame number
%   EndStr     -   Simulation termination string
%   WSstr      -   White space string for screen formatting
%   L1STR      -   Output window title string
%   L2STR      -   Output window subtitle string
%   PSTR       -   Percent complete string
%   guiPax     -   Object handle percent complete axes
%   f1         -   Object handle for startup window
%   hh         -   Object handle for miscellaneous window objects
%   YesButton  -   Object handle for startup YES button
%   NoButton   -   Object handle for startup NO button
%   OKButton   -   Object handle for OK termination button
%   ss         -   Screen size vector for host machine
%   xorg       -   Host machine screen X axis origin for output window
%   yorg       -   Host machine screen Y axis origin for output window
%   x          -   X coordinates for percentage complete rectangle
%   y          -   Y coordinates for percentage complete rectangle
%   F1POS      -   Output window location in screen pixels
%
% GLOBALS
%   guiState   -   Graphical output or status output mode
%                  0 = status mode (non-interactive), 1 = graphics mode
%   guiF1      -   Output window object handle
%   guiSline   -   Status output text object handle
%   guiIfile   -   Input file name
%   guiOfile   -   Output file name
%   FrameCnt   -   Number of frames processed so far
%
% CONSTANTS
%    L1POS     -   Text line 1 position in output window (pixels)
%    L2POS     -   Text line 2 position in output window (pixels)
%    L3POS     -   Text line 3 position in output window (pixels)
