Easiest way to convert a string into a HashMap
<p>if I have some text in a String like:</p>

<blockquote>
  <p>"abc=123,def=456,ghi=789"</p>
</blockquote>

<p>how could I create a populated <code>HashMap&lt;String,Int&gt;</code> object for it in the easiest, shortest amount of code possible in Kotlin?</p>
