Platform Language API and Language Implementations

[VISTALL]

Current examples:

• JVM platform
  • Java
  • Groovy
  • Kotlin
  • Scala
• .NET platform
  • C#
  • F#
  • Visual Basic

For example need create line marker provider for xClass and some marker like xAttribute/xAnnotation. Some languages same interfaces like DotNetType or PsiClass.

But anyway need create own xProvider for each language.

.NET plugin/Java plugin already provide some abstraction for it like DotNetType / JvmClass / PsiClass

How it will be - creating with to classes:

public class JvmLanguage extends xApiLanguage {
}

public class JavaLanguage extends Language implements LanguageImplement {
    public XApiLanguage getParentLanguage() {
       return JvmLanguage.INSTANCE; 
    }
}

Api language is not registered as parent of Impl since, it's not share tokens, etc.

Also need some convertor which will convert Impl Classes to Api classes.
