first files added, files needed to build the Units object
and have the definitions
Add the unit_error object and warning for non given unit
Makefiles
Documentation changes for unit, a little start in the
parsing file, a change in doxygen package call, created
antioch.sty, easier and enable personal commands
Documentation added
Almost all tests are ok, only the parsing part is not done
A small addition for the parsing part:
a simple macro to piss off any user who do not
provide explicitely all the parameters
Default values of scale (R) changed from R/1000. to R
Parsing done, much more documentation along with detailed units
checks
Small change to make it a little bit more beautiful
