this progress extracts drifter data(coordinates) based on time range, geographic range or drifter id, then plot them.
The ouput file will be in same folder as this program. 
input values: time period,gbox(maxlon, minlon,maxlat,minlat),or time period and id
function uses: getobs_drift_byrange,getobs_drift_byidrange,colors,getobs_drift_byid
output : a plot file to show drifter track.
