Imports
com.github.javaparser.ast.Node, .NodeList, com.github.javaparser.ast.type.Type, com.github.javaparser.metamodel.DerivedProperty, java.util.Optional
A node that can have type arguments. 

    new X();        --> typeArguments == Optional is empty
    new X<>();      --> typeArguments = [], diamondOperator = true
    new X<C,D>();   --> typeArguments = [C,D], diamondOperator = false
Only ObjectCreationExpr uses the diamond operator. On other nodes it is treated the same as the first case.
