started to convert abstract dotlinker class
Moving things to abstract class AbstractDotLinker Finished
fixed innerclass Particle calling
refactoring file structure, pakcagings.
DotLinkerHeadless added, for loading data directly by java arrays.
fixed package paths
interface LinkCosts moved to under emblcmci.linker.costfunctions
moved all scripts to under src/test/scripts
test jython script added. 
DotLinkerHeadless.java.
gitignore added with pydev related eclipse config file.
Created new classes Node and Track under emblcmci.obj. Both were
originally inner class of ViewDynamics class, but for generality they
were taken out. Also for thinking about how to design objects in the
tools, and to integrate them.
tracking using points derived by Maxima finder is not working from
jython script.
started working on TrackReLinker.
Plotting gaps (a frame without point detected was ignored from plotting)
is now fixed.
Preparation for the relinking class done.
.gitignore updated
relinker coding in progress, before the actual algorithm implementation.
Relinking algorithm implemented. 
Uses modified Visitor pattern of Tracks (Elements) <-> Analysis
(Visitor)
Relinking gaps between tracks: working upto get candidate linkings.
relinking between gaps workinng OK.
