eina: add an example to demonstrate different eina insert and sort functions.

Summary:
While going through eina for understanding, wrote  a program to understand
he differences between different eina inarray functions. Thought, this might
be useful for others too, so adding the same.

* This example creates an inline array of integers, and demonstrates the
* difference between eina_inarray_insert and eina_inarray_sort, and
* eina_inarray_search and eina_inarray_search_sort.
* @ref eina_inarray_example_01.
*
* We start with some variable declarations and eina initialization:
* @skip int
* @until eina_init
*
* We then create the array much like we did on @ref eina_inarray_example_01 :
* @until inarray_new
*
* We then add element using eina_inarray_insert and print. Then remove that
* element and add again using eina_inarray_insert_sorted and prints. This
* shows the 2 different positions the elment gets added. Then searches an
* element in the unsorted array using eina_inarray_search, then sorts the
* array and then searches the same element using eina_inarray_search_sorted.
* @until }
