-Double Ended Queue
-==================
-Tucker Evans
-v1.0, 2020-06-10
-
-A double ended queue implemented in a circular buffer.
-
-NOTE: There is currently no way to distinquish between a failed retrieval
-(pop_front, index, back, etc.) and returning a NULL value. Keep this in mind if
-you plan on storing NULL values in the queue, there are plans to fix this in
-the future.
-
-Types
------
-
-+deq+
-~~~~~
-This structure holds all internal information regarding a double ended queue.
-All functions (except constructors) expect a pointer to this struct as their
-first parameter.
-
-Functions
----------
-
-+deq* deq_new()+
-~~~~~~~~~~~~~~~~
-Constructs an empty double ended queue.
-
-Examples
-^^^^^^^^
-[source,c]
-----
-#include "double_ended_queue.h"
-
-deq *queue = deq_new();
-----
-
-`deq* deq_with_capacity(int capacity)`
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Constructs an empty double ended queue with space for +capacity+ items.
-
-Examples
-^^^^^^^^
-[source,c]
-----
-#include "double_ended_queue.h"
-
-deq *queue = deq_with_capacity(16);
-----
-
-+int deq_size(deq *self)+
-~~~~~~~~~~~~~~~~~~~~~~~~~
-Returns the number of elements in queue +self+.
-
-Examples
-^^^^^^^^
-[source,c]
-----
-#include "double_ended_queue.h"
-
-deq *queue = deq_new();
-assert(deq_size(queue) == 0);
-deq_push_back(queue, NULL);
-assert(deq_size(queue) == 1);
-----
-
-+int deq_capacity(deq *self)+
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Returns the maximun number of elements in queue +self+ before the buffer needs
-to be resized.
-
-Examples
-^^^^^^^^
-[source,c]
-----
-#include "double_ended_queue.h"
-
-deq *queue = deq_with_capacity(16);
-assert(deq_capacity(queue) == 16);
-----
-
-+deq* deq_cp(deq *self)+
-~~~~~~~~~~~~~~~~~~~~~~~~
-Returns a copy of the queue +self+.
-All elements are kept in the same order however the placement in the buffer may
-change.
-
-Examples
-^^^^^^^^
-[source,c]
-----
-#include "double_ended_queue.h"
-#include <string.h>
-
-char *str1 = "ONE";
-char *str2 = "TWO";
-
-deq *queue = deq_with_capacity(16);
-deq_push_back(queue, str_dup(str1));
-deq_push_back(queue, str_dup(str2));
-
-deq *new = deq_cp(queue);
-assert(strcmp(deq_pop_back, str2) == 0);
-assert(strcmp(deq_pop_back, str1) == 0);
-----
-
-+void deq_free(deq *self)+
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-Frees all internal memory and +self+.
-
-NOTE: All item pointers are still valid after a call to +deq_free+, deq_clear
-should be called before if they are no longer needed to avoid memory leaks.
-
-Examples
-^^^^^^^^
-[source,c]
-----
-#include "double_ended_queue.h"
-
-deq *queue = deq_new();
-deq_free(queue);
-----
-
-+void deq_clear(deq *self)+
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Free all elements within queue +self+, and sets queue to empty (size 0).
-
-NOTE: Does not free internal memory of +self+ or +self+ itself, if this is desired +deq_free()+ should be called immediatly after this.
-
-Examples
-^^^^^^^^
-[source,c]
-----
-#include "double_ended_queue.h"
-#include <string.h>
-
-char *str1 = "ONE";
-char *str2 = "TWO";

-assert(deq_size(queue) == 0);
-deq_free(queue);
-----
-
-+void deq_push_front(deq *self, void *item)+
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Pushes +item+ into front of +self+. This may cause a resize of internal buffer.
-
