 *  Semaphore Manager
3
 *
4
 *  DESCRIPTION:
5
 *
6
 *  This package is the implementation of the Semaphore Manager.
7
 *  This manager utilizes standard Dijkstra counting semaphores to provide
8
 *  synchronization and mutual exclusion capabilities.
9
 *
10
 *  Directives provided are:
11
 *
12
 *     + create a semaphore
13
 *     + get an ID of a semaphore
14
 *     + delete a semaphore
15
 *     + acquire a semaphore
16
 *     + release a semaphore
