/*Class:trace
NAME: @code{trace} - restriction to boundary values operator
@cindex trace operator
@clindex trace
@clindex form
@clindex space
@clindex field
DESCRIPTION:
The @code{trace} operator restricts a field to its values located to a
boundary value domain.
The @code{trace} class is a derived class of the @code{form} class
(@pxref{form class}).
Thus, all operations, such as linear algebra, that applies
to @code{form}, applies also to @code{trace}.
EXAMPLE:
The following example shows how to plot the
trace of a field, from standard input:
@example
int main() @{
geo omega ("square");
space Vh (omega "P1");
space Wh (omega, "P1", omega ["top"]);
trace gamma (Vh, Wh);
field uh;
cin >> uh;
field wh (Wh);
wh = gamma*uh;
cout << wh;
@}
@end example
