Question for Contribution and KeySpace

[Waqas]

Why we need to mention default keyspace? For example
describe_keyspaces (please do not mix it with describe_keyspace)
function does not require a keyspace.

Also i saw closing tags in php classes which i believe is not good at
all.

I have following suggestion:

1. In PandraCore, there should be a setKeySpace method which sets the
keyspace.
2. No dobut closing tags having enter after them should be removed
3. Instead of using the constant, i think setter method will be
better choice.

I am willing to contribute in Pandra. Can anybody please guide how
should i contribute?
