[Halld-offline] vertex position from hit-based tracks

[Craig Bookwalter]

Hi folks,
    I'm looking for a couple methods to help me determine the event 
start time, namely:
    - a method for getting the vertex position of a hit-based track in 
the CDC or FDC
    - a method for getting the path length along a hit-based track from, 
say, the start counter to the target (this would require some 
association between start counter hits and CDC/FDC tracks, which I'm not 
sure is happening yet)

    I've looked through the DOxygen docs and haven't seen anything that 
stuck out to me, but I certainly could have missed something. If these 
guys do not yet exist I would be happy to help implement them.

    Thanks in advance!
