bug fix in the pagination

Hi, great class, but we have to fix just some things like the number of the displayed pages when you are in the middle, for example:

$total = 191;
$results_per_page = 10;

if you go to page number 16 the displayed pages are 10,
if you go to page number 17 are 9
if you go to page number 18 are 8
if you go to page number 19 are 7
if you go to page number 20 are 6

in my opinion the number of the page must to be ever 10.

How we can fix it?

Thank you!

Hi! thanks for comment, The class uses pure mathematics to calculate the number of pages to show.

Example with yours values:

$total = 191;
$results_per_page = 10;
// in this case a total of 19 pages.

Well, the class is ready to not show pages 'nonexistent' what happens reductions resulting nodes, for example:

// if you're on page 11, you will see this
First Prev 6 7 8 9 10 [11] 12 13 14 15 Next Last

// Now, if you're on page 18, you will see this:
First Prev 13 14 15 16 17 [18] 19 Next Last
// The amount reduced because the pages 20, 21 and 22 do not exist (whether to display null values ​​then be displayed)

I hope I explained well, in any case I am at your disposal :)
