## Detailed Description

vector of ints.

It's used to store indices, it has similar functions as VOL_dvector.

Note: If `VOL_DEBUG` is `defined` to be 1 then each time an entry is accessed in the vector the index of the entry is tested for nonnegativity and for being less than the size of the vector. It's good to turn this on while debugging, but in final runs it should be turned off (beause of the performance hit).
