Implemented domain.print_mesh_info() so we can see the distribution of elements & nodes.
Implemented -DBOUNDS_CHECK to catch an error with periodicN=True.

21 /* Finley: Mesh */
22
23 /* A mesh is built from nodes and elements which are describing the
24 domain, the surface and point sources. (the latter are needed to
25 establish links with other codes, in particular to particle
26 codes). The nodes are stored a Finley_NodeFile and elements in a
27 Finley_ElementFile. A Finley_NodeFile and three Finley_ElementFile
28 containing the elements describing the domain, surface and point
29 sources respectively. Notice that the surface elements do not
30 necessaryly cover the entire surface of the domain. */
31
32 /* The element type is fixed by the reference element, see
33 ReferenceElement.h. The numbering of the nodes starts with 0. */
34
35 /* Important: it is assumed that every node is appearing in at least
36 one element or surface element and that any node used in an
37 element, surface element or as a point is specified in the
38 Finley_Node, see also Finley_resolveNodeIds. */
39
40 /* In some cases it is useful to refer to a mesh entirly built from
41 order 1 (=linear) elements. The linear version of the mesh can be
42 accessed by referning to the first few nodes of each element
43 (thanks to the way the nodes are ordered). As the numbering of
44 these nodes is not continuous a relabeling vectors are introduced
45 in the Finley_NodeFile. This feature is not fully implemented
46 yet. */
47
48 /* allnodes and elements are tagged. the tag allows to group nodes and
49 elements. A typical application is to mark surface elements on a
50 certain portion of the domain with the same tag. All these surface
51 elements can then assigned the same value eg. for the pressure. */
52
53 /* Thespacial dimension is determined by the type of elements
54 used. The spacial dimension should be accessed by the function
55 Finley_Mesh_getDim. Notice that the element type also determines
56 the type of surface elements to be used. */
