/** A collection of decorators that allow converting between
 *  Scala and Java collections using `asScala` and `asJava` methods.
 *
 *  The following conversions are supported via `asJava`, `asScala`
 *
 *  - `scala.collection.Iterable` <=> `java.lang.Iterable`
 *  - `scala.collection.Iterator` <=> `java.util.Iterator`
 *  - `scala.collection.mutable.Buffer` <=> `java.util.List`
 *  - `scala.collection.mutable.Set` <=> `java.util.Set`
 *  - `scala.collection.mutable.Map` <=> `java.util.Map`
 *  - `scala.collection.mutable.concurrent.Map` <=> `java.util.concurrent.ConcurrentMap`
 *
 *  In all cases, converting from a source type to a target type and back
 *  again will return the original source object, e.g.
 *  {{{
 *    import scala.collection.JavaConverters._
 *
 *    val sl = new scala.collection.mutable.ListBuffer[Int]
 *    val jl : java.util.List[Int] = sl.asJava
 *    val sl2 : scala.collection.mutable.Buffer[Int] = jl.asScala
 *    assert(sl eq sl2)
 *  }}}
 *  The following conversions also are supported, but the
 *  direction Scala to Java is done my a more specifically named method:
 *  `asJavaCollection`, `asJavaEnumeration`, `asJavaDictionary`.
 *
 *  - `scala.collection.Iterable` <=> `java.util.Collection`
 *  - `scala.collection.Iterator` <=> `java.util.Enumeration`
 *  - `scala.collection.mutable.Map` <=> `java.util.Dictionary`
 *
 *  In addition, the following one way conversions are provided via `asJava`:
 *
 *  - `scala.collection.Seq` => `java.util.List`
 *  - `scala.collection.mutable.Seq` => `java.util.List`
 *  - `scala.collection.Set` => `java.util.Set`
 *  - `scala.collection.Map` => `java.util.Map`
