Remove index value for existing object

[pavelsmolka]

Let $object be \Riak\Object. It is easy to add new values to be indexed via secodary index (available for leveldb):

$object->addIndex($indexName, $indexValue);

When the $object already have some index values, it is also possible to read them, such as:

$indexMap = $object->getIndexMap();

However, there is no option to remove an existing index. This would be particularly useful when updating an existing record (re-writing $object retrieved via $object = $riakEntity->getFirstObject();). If I need to remove an existing index, I need to create a new Riak\Object and copy all values. It would be nice to have a method to remove an existing index, such as:

$object->removeIndex($indexName);

If you agree with the proposed change, I can try to implement it.

Hi
Sound like a good idea, I do not have much time to work on this project at the moment, so you very welcome to try and implement it.
