title: How can i add custom expression functions for Live templates in Intellij
body: <p>How can add new custom functions for Live Templates in Idea Intellij.</p>
  
  <p>For example i need a custom function which can convert a live template variable from Camel Case to Spaced.
  i.e in Live Template on variable has to be inserted at multiple places with &amp; without space.</p>
  
  <p>Eg.   "MyVar" and "My Var". So i want to insert an expression to convert 'MyVar' to 'My Var'.</p>
  
  <p>No expression available by default can be used for this.</p>
  
  <p>Thanks.</p>
