Changes to enable building with SciDB 13.11.
Added convenient env variable settings to CMakeLists.
Added correct link options in CMakeLists.
Fixed code to work with updated DBArray API.
Fix load for compatibility with 13.11.
Must explicitly set "isRLE" to false for raw chunks.
Must make sure load is "coordinator-only".
Use chunk iterators to copy data into SciDB.  This is the only supported method for putting data in chunks going forward.
Note: load will fail if "redundancy" is not set to "0".  This will be fixed in future change.
Update loader to support distribution of data on multiple instances.
'loadhdf' AFL function no longer writes directly to disk.  Instead it returns
a temporary array to its caller.  This allows us to wrap the load function in
a 'store()' operation which will take care of distributing data to multiple instances
with proper replication.  TODO:  now the 'loadhdf' operation is a blocking op...
it loads the data entirely into a temporary array before completion.  A more
efficient solution would be to implement it as a 'delegate' array and load the
data lazily as it is pulled by the 'store()' operator.
Update README file to reflect recent changes to 'loadhdf' signature.
Merge branch 'master' of https://github.com/sfridellap4/SciDB-HDF5 into integrate-sfridellap4
