Add MockBase.java, a mock implementation of HBase used for unit testing.
It uses nested hash tables to store keys as hex encoding strings with
byte arrays as the value. It does not currently support timestamps or
multiple versions. The asyncbase client is mocked with the following:
GetRequest
DeleteRequest
PutRequest
CompareAndSet
Scanner (limited to row regex and always returns the entire result in
  the first call)
AtomicIncrementRequest
