file: c/vector.shar

for: Low and Intermediate Level functions to manage vectors in C.

In fact, the vector declaration as a special structure and
a wide set of procedures to handle it define a class (in
the sence of C++ or SMALLTALK). It is still a common C,
however.
Features: high reliability and fool-proof checking, the
user can operate on single elements of the vector in the
customary C manner, or he may wish to handle the vector as
a whole (as an atomary object) with high-effective functions
(that can clear the vector, assign vectors or obtain their
scalar product, find the vector norm(s), etc.).
