Vector library - allocate and zero array space (lower level functions)
Lower level functions for reading/writing/manipulating vectors.
These routines all eventually call calloc() to allocate and zero the new space. BUT It is not necessarily safe to assume that the memory will be zero. The next memory location asked for could have been previously used and not zeroed. (e.g. compress()).
