Defines a few String Interpolators. Interpolators are things like the built-in s"Hello $name", where the "s" interpolator plugs in the value of the s variable.
To use any of these interpolators, you must use this include: import io.snappydata.util.StringUtils._
TODO: Add some more, e.g., loginfo that prepends Thread name, pid, etc.?
