getpct(pctdone,block)

function [block] = getpct(pctdone,block)
% GETPCT - Returns a value of where the percent bar is.  This was designed
% to replace the waitbar function due to its high overhead.  It only add
% about 10% overhead compared to waitbar's 60-70% overhead.
%
%   [BLOCK] = GETPCT(PCTDONE,BLOCK) - will return the block array with
%       updated values.  PCTDONE is an interger value used to evaluate
%       whether or not to print a percent marker.  Once a value has turned 
%       to 1, then that percent marker can not be used again unless the 
%       BLOCK variable is reset to all zeros.
%
%   EXAMPLE
%
%   pct_count = 1; % BEGINNING VALUE FOR PERCENTAGE BAR
%   pct_skip = 20; % SKIP THIS NUMBER OF LINES BEFORE CHECKING PERCENTAGE AGAIN(SPEED UP ALGORITHM)
%   block = zeros(10,1);
%   disp('LOADING DATA FILE...');
%   for i = 1:1000
%       if pct_count == pct_skip
%           pctdone = floor(100*i/1000);
%           if (pctdone==10)||(pctdone==20)||(pctdone==30)||(pctdone==40)||(pctdone==50)||(pctdone==60)||(pctdone==70)||(pctdone==80)||(pctdone==90)
%               [block] = getpct(pctdone,block);
%           end
%           pct_count = 1;
%       else
%           pct_count = pct_count + 1;
%       end
%       pause(.01);
