New Utility Functions

• GRAPE now has a block memory manager which allows to very efficiently allocate and free large numbers of equally sized small memory blocks, see 10.2.1.2.
• There are new string functions, they should be used instead of the usual C library function to avoid mixing memory allocated with mallac and mem_alloc, see 10.2.9.
• Class G_List has been extended with an iterator stack, this allows to safely use iterators in nested loops, see 10.1.1.1.
• GRAPE now provides some machine-independent time functions, see 10.2.13.
