  * KTable For Sort Parser Transformer

  * Roughly speaking, the transform will turn the following:
  *
  *     // file: Foo.kt
  *     ```kotlin
  *     fun <T: KPojo> T.foo() {
  *          val action: (KTableSortable<T>.(T) -> Unit) = { it: T ->
  *              it.username.desc() + it.password.asc() + it.age
  *          }
  *          KTableSortable<T>().action(this)
  *     }
  *     ```
  *
  * into the following equivalent representation:
  *
  *    // file: Foo.kt
  *    ```kotlin
  *     fun <T: KPojo> foo() {
  *          val action: (KTableSortable<T>.(T) -> Unit) = { it: T ->
  *              addSortField(Field("username",...).desc())
  *              addSortField(Field("password",...).asc())
  *              addSortField(Field("age",...))
  *              it.username.desc() + it.password.asc() + it.age
  *          }
  *          KTableSortable<T>().action(this)
  *    }
  *    ```
