Use GMT to make a multiple panel GAMIT baseline plots  with uncertainty scaling
  
     It  also creates inputs for repeatability(wrms/nrms scatter plots) [use sh_globk_scatter] 
  REQUIRES      : GMT(netcdf/gmt/ghostscript)
                : gamit/utils/poly01
  
  USAGE :    sh_gamit_baseline   <options>.

 -o[files]     list    : ofile names. MUST have this.
 -b[aseline]   list    : Command line argument for baselines.    
 -f[ile]       file    : Baseline names file. 
 	If -f and -b are both omitted, all baselines are plotted.
 -free                 : Biases free solution. Default.
 -fixed                : Biases fixed solution.
 -d[elete] <sites/blines> : Names of unwanted sites.
 -delete_file file     : File contains the names of unwanted sites. 
 -u[nc_scale]  ###     : Scale all uncertainties with this number. Default is 1.
 -y[scale]   min max   : Vertical scale.  If not issued it will be calculated.
 -x[scale]   min max   : Horizontal scale.  If not issued it will be calculated.
 -frame      value     : GMT border day-axis frame  ticks. Default is  1. 
 -anot       value     : GMT border day-axis label intervals. Default is  1. 
 -a          ext       : Add more descriptors to postscript file name. Default is psgamit.#
 -opt      <option>    : Functional options: noextract - skip extraction, redo plot.
