Fixing sample project and switch to gradle dependencies

[CreatorB]

Hi neokree, nice repo 👍 and helped me, but some code's error after cloned, now have been fixed and some changes added.

• Added demo fragment
• Deleted module and replaced by gradle dependencies

hope will be easier to use

Is there still a need for this library? Instead you could use the tab implementation of the support design library which is backwards compatible upto SDK 7

See: http://www.androidhive.info/2015/09/android-material-design-working-with-tabs/

@locationad yep, but when i used 5 tab, whatever support design library or neokree library still return me to error 'index overflow' and then make it app closed immediately 😕 maybe someone there can bring me throught out
