The file fixedarray.hh is renamed to array.hh, to conform with the name of the class it contains.  A backward-compatibility stub will be checked in in a second

Added assign methode as ther is no operator=(const T&) in std::tr1::array<T,int>.

The segfault I reported remains extremely elusive, I have not been able to reliably
reproduce it, let alone track iit down.  On the other hand, my production codes runs 
smoothly with this patch.

Also, FixedArray is deprecated now.

because it caused an extremely strange segfault.  No idea why.

Use system implementation of 'array' if present.  Deprecate constructor array(const T& t) because the libstd++ implementation doesn't have it

[[Imported from SVN: r4933]]

Added a class 'array' which provides the same functionality as FixedArray, but conforms to the naming
of the tr1 array class.  I would have liked to put this into a separate header, but unfortunately,
array.hh exists already.  In a future step, the stl implementation of 'array' will be used when
available.

File, ebenso Vec, daß sich in fixedvector.hh befindet.
Außerdem erbt Vec jetzt von FixedArray.  Leider sind
einige Änderungen nicht rückwärtskompatibel.  Insbesondere
fehlen Vec::print (man nehme stattdessen operator<<)
und Vec::read (man nehme const T& operator[])
Entschuldigt die Unannehmlichkeiten.
