Examples of org.apache.commons.configuration.Configuration.addProperty()

org.apache.commons.configuration.Configuration.addProperty()
Add a property to the configuration. If it already exists then the value stated here will be added to the configuration entry. For example, if the property:
```
resource.loader = file
```
is already present in the configuration and you call
```
addProperty("resource.loader", "classpath")
```
Then you will end up with a List like the following:
```
["file", "classpath"]
```
@param key The key to add the property to. @param value The value to add.
