title: How do you change a showcaseview circle radius?
body: <p>I use the master code from git repo of the showcaseview library.</p>
  
  <p>Since am new to setting up this library, I am not sure how one can reduce the size of the circle indicator.</p>
  
  <p>Some legacy code contained config options where you can set the radius, but i couldn't find a source which has customising the same in the master repo.</p>
