Servicing missions and new instruments
Done as See Timeline and Timeline syntax

To do
Could add :
 * extend to 2017 (01/Mar/2017 rejected, 2017 = whole year ? 2017.4 accepted - maybe rounding up ?)
 * move WPFC left (somehow override default positioning - ? from:1991 ? )
 * all text starts in centre of sub-bar - want text centred within each sub-bar
 * see if divisions done at start or mid year - Use dd/mmm/yyyy to make more accurate ?
 * periods of degraded operation - instruments esp NICMOS
 * may need to split bar into 3 (if can't do half width bar eg with LineData at:time )
 * or add Line and eg from:1935 till:2004 text:"broken" color:writer
 * add a Legend (description)
 * Show which position/slot each is in (label each bar on vertical axis ?)(why 5 not 4 ??
 * Servicing mission dates (can we have a blank bar and draw "^" or triangles ?)
 * extra bar for periods of degraded operation of spacecraft
