/*****************************************************************
The class ZZVec implements vectors of fixed-length ZZ's.
You can allocate a vector of ZZ's of a specified length, where
the maximum size of each ZZ is also specified.
These parameters can be specified once, either with a constructor,
or with SetSize.
It is an error to try to re-size a vector, or store a ZZ that
doesn't fit.
The space can be released with "kill", and then you are free to
call SetSize again.
If you want more flexible---but less efficient---vectors,
use vec_ZZ.
