The automatic tests have shown that the code was getting slower following the latest commits. After investigations (thanks valgrind!), it has been found that the newly added copy constructor of Coords was used a lot as well as setFunctionPointers(). Therefore the function pointers have been removed and replaced by a simple list of if(coordsy=="") etc. The run time is now back to normal (and actually up to 6% faster on some tests). Cosmetic touch up on Date.
