/** @defgroup default_store storage space for defaults 
 *  @ingroup library
 *
       The purpose of the default storage is three-fold:

       1)     To create a global storage space without creating a
              whole  bunch  of globally accessible variables or a
              whole bunch of access functions to work  with  more
              privately restricted variables.

       2)     To provide a single location where the thread lock-
              ing needs to be implemented. At the  time  of  this
              writing,  however,  thread  locking  is  not yet in
              place.

       3)     To reduce the number of cross dependencies  between
              code  pieces that may or may not be linked together
              in the long run. This provides for a  single  loca-
              tion  in which configuration data, for example, can
              be stored for a separate section of code  that  may
              not be linked in to the application in question.

       The functions defined here implement these goals.

       Currently, three data types are supported: booleans, inte-
       gers, and strings. Each of these data types have  separate
       storage  spaces.  In  addition, the storage space for each
       data type is divided further  by  the  application  level.
       Currently,  there  are  two  storage  spaces. The first is
       reserved for  the  SNMP  library  itself.  The  second  is
       intended  for  use  in applications and is not modified or
       checked by the library, and, therefore, this is the  space
       usable by you.

14		/** @defgroup default_store storage space for defaults
15		* @ingroup library
16		*
17		The purpose of the default storage is three-fold:
18
19		1) To create a global storage space without creating a
20		whole bunch of globally accessible variables or a
21		whole bunch of access functions to work with more
22		privately restricted variables.
23
24		2) To provide a single location where the thread lock-
25		ing needs to be implemented. At the time of this
26		writing, however, thread locking is not yet in
27		place.
28
29		3) To reduce the number of cross dependencies between
30		code pieces that may or may not be linked together
31		in the long run. This provides for a single loca-
32		tion in which configuration data, for example, can
33		be stored for a separate section of code that may
34		not be linked in to the application in question.
35
36		The functions defined here implement these goals.
37
38		Currently, three data types are supported: booleans, inte-
39		gers, and strings. Each of these data types have separate
40		storage spaces. In addition, the storage space for each
41		data type is divided further by the application level.
42		Currently, there are two storage spaces. The first is
43		reserved for the SNMP library itself. The second is
44		intended for use in applications and is not modified or
45		checked by the library, and, therefore, this is the space
46		usable by you.
