Add sampleCode property to Assay
Deprecated stuff fot the old high dim API

Though there's no way to query for aCGH data through the new interface
at this point.
Add new high dimensional data retrieval API
Merge branch high_dim_new_api into thehyve/master
Add well-known data constraint: disjunction
Disjunction constrint spec changes

Described how several subcontraints of the same type are to be
specified.
Remove old high dim api; adapt acgh stuff to new 1
Add property Assay.patientInTrialId
Add gene, protein and analyte data constraints constants
Move Region to anoth. package; rem redundant field
Add HighDimensionResource::getKnownTypes()
Region::getNumberOfProbes() is needed after all
Comment change
Add new keyword-type specific constraints
Rename constraint constant for consistency
Make DataRow implement Iterable
Make TabularResult Iterable.

The implementation in core-db is actually already iterable, so no
changes are needed there.
Add BioMArkerDataRow
Move constants for well-known projections here

Better docs for Projection as well.
Remove PlatformMarkerType

Having an enumeration in the API of the available platform marker
types is not a viable strategy in the current high dimensional API
where new data types (and hence new platform marker types) can be
plugged in.
