+ situations, a routine installed with 'atexit()' would jump to a routine
+ which was no longer in memory, causing errors.
+ In order to be effective, this routine _must_ be called before any other
+ HDF function calls, and must be called each time the library is loaded/
+ linked into the application. (the first time and after it's been un-loaded)
+ GLOBAL VARIABLES

+ although in theory a user could call HPend on their own...

+ atom.c - Internal storage routines for handling "atoms"
+
+REMARKS
+ Atoms are just ID's which allow objects (void *'s currently) to be
+ bundled into "groups" for more general storage.
+
+DESIGN
+ The groups are stored in an array of pointers to store each group in an
+ element. Each "atomic group" node contains a link to a hash table to
+ manage the atoms in each group. The allowed "atomic groups" are stored
+ in an enum (called group_t) in atom.h.
+
+BUGS/LIMITATIONS
+ Can't interate over the atoms in a group.
+
+LOCAL ROUTINES
+ H5A_find_atom - Returns a pointer to an atom_info_t from a atom ID
+ H5A_get_atom_node - Gets an atom node (uses the atom free list)
+ H5A_release_atom_node - Releases an atom node (uses the atom free list)
+EXPORTED ROUTINES
+ Atom Functions:
+ H5Aregister_atom - Register an object in a group and get an atom for it
+ H5Aatom_object - Get the object for an atom
+ H5Aatom_group - Get the group for an atom
+ H5Aremove_atom - Remove an atom from a group
+ H5Asearch_atom - Search a group for a particular object
+ H5Ais_reserved - Check whether an atom is a reserved atom in a group
+ Atom Group Functions:
+ H5Ainit_group - Initialize a group to store atoms in
+ H5Adestroy_group - Destroy an atomic group
+ Atom Group Cleanup:
+ H5Ashutdown - Terminate various static buffers.

+ * Robb Matzke <robb@maya.nuance.com>
+ *
+ * Purpose: Implements balanced, sibling-linked, N-ary trees
+ * capable of storing any type of data with unique key
+ * values.
+ *
+ * A B-link-tree is a balanced tree where each node has
+ * a pointer to its left and right siblings. A
+ * B-link-tree is a rooted tree having the following
+ * properties:
+ *
+ * 1. Every node, x, has the following fields:
+ *
+ * a. level[x], the level in the tree at which node
+ * x appears. Leaf nodes are at level zero.
+ *
+ * b. n[x], the number of children pointed to by the
+ * node. Internal nodes point to subtrees while
+ * leaf nodes point to arbitrary data.
+ *
+ * c. The child pointers themselves, child[x,i] such
+ * that 0 <= i < n[x].
+ *
+ * d. n[x]+1 key values stored in increasing
+ * order:
+ *
+ * key[x,0] < key[x,1] < ... < key[x,n[x]].
+ *
+ * e. left[x] is a pointer to the node's left sibling
+ * or the null pointer if this is the left-most
+ * node at this level in the tree.
+ *
+ * f. right[x] is a pointer to the node's right
+ * sibling or the null pointer if this is the
+ * right-most node at this level in the tree.
+ *
+ * 3. The keys key[x,i] partition the key spaces of the
+ * children of x:
+ *
+ * key[x,i] <= key[child[x,i],j] <= key[x,i+1]
+ *
+ * for any valid combination of i and j.
+ *
+ * 4. There are lower and upper bounds on the number of
+ * child pointers a node can contain. These bounds
+ * can be expressed in terms of a fixed integer k>=2
+ * called the `minimum degree' of the B-tree.
+ *
+ * a. Every node other than the root must have at least
+ * k child pointers and k+1 keys. If the tree is
+ * nonempty, the root must have at least one child
+ * pointer and two keys.
+ *
+ * b. Every node can contain at most 2k child pointers
+ * and 2k+1 keys. A node is `full' if it contains
+ * exactly 2k child pointers and 2k+1 keys.
+ *
+ * 5. When searching for a particular value, V, and
+ * key[V] = key[x,i] for some node x and entry i,
+ * then:
+ *
+ * a. If i=0 the child[0] is followed.
+ *
+ * b. If i=n[x] the child[n[x]-1] is followed.
+ *
+ * c. Otherwise, the child that is followed
+ * (either child[x,i-1] or child[x,i]) is
+ * determined by the type of object to which the
+ * leaf nodes of the tree point and is controlled
+ * by the key comparison function registered for
+ * that type of B-tree.

+ * split) will be at a new file address.
