N Lin test egit with a test Domain1DMapper.
Modifications according to code review.
Modify GridCoordinatas2D class: let it implement Comparable interface.
So, in the test class of Domain1DMapper, the container, an ordered
TreeMap<GridCoordinatas2D, List<Integer>> can be created.
Add copy right description, javadoc, and comments for 12 test classes.
Add TimeAxisImplTest, which is to replace TimeAxisTest. The version of
GridCoordinates2D implements Comparable interface as a test class need
this function.
Modifications including putting copy right sections and Java doc.
GridCoordinate2D should not implement Comparable interface.
Domain1DMapper test code is changed accordingly.
