Inheritable properties for a class.
You can put in properties for a class of objects in here, and then retrieve them by specifying a class or by passing in an object. There are two advantages to putting key-values in here over putting them as static values in the class:

Given a class and a property name, generate a key. |
String |
generateDefaultKey(String key)
Generate the default value for a key. |

getClassProperty(Class cl,

Object |
removeClassProperty(Class cl,
String key)
Remove the property for this class and key. |
void |
setClassProperty(Class cl,

Object newVal)
Put a property in for this class, overriding an old value if there is one. |

public String generateClassKey(Class cl, String key)
public String generateDefaultKey(String key)
public Object getClassProperty(Class cl, String key)
Keep in mind that this gets a reference to the specified key. Thus, if you modify the retrieved value, you modify it for everyone. You may want to make a clone of it first.
