CODATA constants

Originally reported on Google Code with ID 255

Hi,

Some weeks ago I compared the constants with my own collection 
and some other sources. I found much values on some pages but 
different at least in the last digits. Differences bigger than
the given uncertainty. Differences between the same value on
english and german wikipedia and so on.

Thus I downloaded the complete list of CODATA from 
http://physics.nist.gov/cuu/Constants/index.html
and copied it in your source.

The file attachment is a new constants.cpp containing all CODATA
values. I've compile the program with the new source and verified
the values, exponents and units between the single value pages 
nist and the categories in speedcrunch. Units are the same as in 
the  list (m s^-2), not as in your constants.cpp.

For other reasons I've add some values of astronomy and sun system.
These values are from
http://de.wikipedia.org/wiki/Datei:WikiPress_6_Sonnensystem.pdf,
a german wikipress book (copied from pdf file). Values in the form 
of 23 h 56 m 4 s or 23° 26' 22" I've convert to decimal with an 
self-written simple program.
On some values the source is written in the comment.

If you find it useful I could add some conversions yet from
http://physics.nist.gov/cuu/pdf/sp811.pdf

Sincerily, Thomas
