other classes
- implemented archiving for the following classes: color, idx, coloridx,
isospin
- non-crational numbers are now stored in an integer-decoded format in archives

- Macro GINAC_CHECK_LIBCLN only checks if doublefactorial is available now.
If it is, the version is new enough and we can omit the second sanity
test which makes that configure step twice as fast.

agreement with Bruno Haible.

- implemented global class registry (for class basic and derived classes)
- implemented archiving of expressions (except for class idx, and all classes
derived from idx and indexed)
- added series() wrapper function
- class series renamed to pseries to avoid name clashes with global series()
wrapper function, ex::series(), and basic::series()
- corrected the series expansion of single symbols with respect to the order
term
- calling subs() on a series didn't work

series expansion of a simple polynomial

- more logic on the trigonometric function stuff.
- changed several occurences of numeric const & to const numeric &, which
is the same, but doxygen kept being confused because declarations
differed from implementations.

to extend them as it pleases you but use them inside the library only.

check/differentiation.cpp to account for this.
