Description
We needs an implementation of JSR-363 to be used as a replacement of JSR-275. This is needed since the JSR-275 specification attempt has been rejected. Some existing implementations exist, especially the UOMo and JScience projects, but we also have some legacy classes that we could refactor. A possible advantage of the later approach is that we have to support some rather particular Unit, like the one used in NetCDF files (e.g. "degrees_east"), which may be easier in a custom implementation.
