- interpolateString
  
  public static String interpolateString(String templateInput, Map<String,String> valuesMap)
  
  Interpolates a String containing variable placeholders with the values provided in the valuesMap.
  This method is intended to interpolate templates loaded from YAML and JSON files.
  Placeholders are indicated by the dollar sign and curly braces (${VARIABLE_KEY}).
  Placeholders can also be indicated by the dollar sign and double curly braces (${{VARIABLE_KEY}}), when this notation is used, the resulting value will be unquoted (if applicable), expected values should be JSON compatible.
  
  Parameters:
  
  valuesMap - to interpolate in the String
  
  templateInput - raw input containing a String with placeholders ready to be interpolated
  
  Returns:
  
  the interpolated String
