-Alters expBarSprite's fill amount according to % ( exp gained /
required )
-Scales according to viewport
-Used Mathf.Lerp() to smooth bar growth over time.deltatime * lerpSpeed
-Added clicks integer to keep track of total clicks
Needs:
-Delevel if ExpLess() called until expObtained < previousExpRequired
-Create function to query for previous and future level requirements
