/*Class:
NAME: @code{level_set} - compute a level set from a function
@findex level_set
@clindex field
@clindex geo
SYNOPSYS:
geo level_set (const field& fh);
DESCRIPTION:
Given a function @code{fh} defined in a domain @code{Lambda},
compute the level set defined by @{x in Lambda, fh(x) = 0@}.
This level set is represented by the @code{geo} class.
OPTIONS:
The option class @code{leve_set_option_type}
controls the slit of quadrilaterals into triangles
for tridimensional intersected surface and also the
zero machine precision, @code{epsilon}.
End: */
