+There are implementations of 5 classes in this file:
+LocTimer, LocTimerDelegate, LocTimerContainer, LocTimerPollTask, LocTimerWrapper
+
+LocTimer - client front end, interface for client to start / stop timers, also
+           to provide a callback.
+LocTimerDelegate - an internal timer entity, which also is a LocRankable obj.
+                   Its life cycle is different than that of LocTimer. It gets
+                   created when LocTimer::start() is called, and gets deleted
+                   when it expires or clients calls the hosting LocTimer obj's
+                   stop() method. When a LocTimerDelegate obj is ticking, it
+                   stays in the corresponding LocTimerContainer. When expired
+                   or stopped, the obj is removed from the container. Since it
+                   is also a LocRankable obj, and LocTimerContainer also is a
+                   heap, its ranks() implementation decides where it is placed
+                   in the heap.
+LocTimerContainer - core of the timer service. It is a container (derived from
+                    LocHeap) for LocTimerDelegate (implements LocRankable) objs.
+                    There are 2 of such containers, one for sw timers (or Linux
+                    timers) one for hw timers (or Linux alarms). It adds one of
+                    each (those that expire the soonest) to kernel via services
+                    provided by LocTimerPollTask. All the heap management on the
+                    LocTimerDelegate objs are done in the MsgTask context, such
+                    that synchronization is ensured.
+LocTimerPollTask - is a class that wraps timerfd and epoll POXIS APIs. It also
+                   both implements LocRunnalbe with epoll_wait() in the run()
+                   method. It is also a LocThread client, so as to loop the run
+                   method.
+LocTimerWrapper - a LocTimer client itself, to implement the existing C API with
+                  APIs, loc_timer_start() and loc_timer_stop().

+FUNCTION loc_split_string
+
+DESCRIPTION:
+    This function is used to split a delimiter separated string into
+    sub-strings. This function does not allocate new memory to store the split
+    strings. Instead, it places '\0' in places of delimiters and assings the
+    starting address of the substring within the raw string as the string address
+    The input raw_string no longer remains to be a collection of sub-strings
+    after this function is executed.
+    Please make a copy of the input string before calling this function if
+    necessary
+
+PARAMETERS:
+    char *raw_string: is the original string with delimiter separated substrings
+    char **split_strings_ptr: is the arraw of pointers which will hold the addresses
+                              of individual substrings
+    int max_num_substrings: is the maximum number of substrings that are expected
+                            by the caller. The array of pointers in the above parameter
+                            is usually this long
+    char delimiter: is the delimiter that separates the substrings. Examples: ' ', ';'
+
+DEPENDENCIES
+    N/A
+
+RETURN VALUE
+    int Number of split strings
+
+SIDE EFFECTS
+    The input raw_string no longer remains a delimiter separated single string.
+
+EXAMPLE
+    delimiter = ' ' //space
+    raw_string = "hello new user" //delimiter is space ' '
+    addresses  =  0123456789abcd
+    split_strings_ptr[0] = &raw_string[0]; //split_strings_ptr[0] contains "hello"
+    split_strings_ptr[1] = &raw_string[6]; //split_strings_ptr[1] contains "new"
+    split_strings_ptr[2] = &raw_string[a]; //split_strings_ptr[2] contains "user"
