public class ClassInfo extends Object
Handle for all information we want to keep about the class
 This class handles caching internally and its advisable to not store
 references directly to objects of this class.  The static factory method
 ClassInfo.getClassInfo should be used to retrieve an instance
 from the cache.  Internally the Class associated with a ClassInfo
 instance is kept as WeakReference, so it not safe to reference
 and instance without the Class being either strongly or softly reachable.

 Returns the MetaClass for the Class associated with this ClassInfo.
 If no MetaClass exists one will be created.
 
 It is not safe to call this method without a Class associated with this ClassInfo.
 It is advisable to aways retrieve a ClassInfo instance from the cache by using the static
 factory method ClassInfo.getClassInfo to ensure the referenced Class is
 strongly reachable.
     
MetaClass instance Returns the Class associated with this ClassInfo.
 
 This method can return null if the Class is no longer reachable
 through any strong or soft references.  A non-null return value indicates that this
 ClassInfo is valid.
     
Class associated with this ClassInfo, else null Removes a ClassInfo from the cache.
 This is useful in cases where the Class is parsed from a script, such as when
 using GroovyClassLoader#parseClass, and is executed for its result but the Class
 is not retained or cached.  Removing the ClassInfo associated with the Class
 will make the Class and its ClassLoader eligible for garbage collection sooner that
 it would otherwise.
