	Select a region in the current Slice/Dataset of count points at offset separated by stride. If strides are not provided they will default to 1 in all dimensions.
Selection	select (const ElementSet &elements) const
	Select a region in the current Slice/Dataset out of a list of elements.
Selection	select_rows (const std::vector< size_t > &ind, size_t offset=0, size_t count=0) const
	Select a set of rows in the first dimension of this dataset. NOTE: Selection is done in memory layout order (be careful with chunked dsets). Most likely the order of rows read will be mixed.
Selection	select_cols (const std::vector< size_t > &ind, size_t offset=0, size_t count=0) const
	Select a set of columns in the last dimension of this dataset. NOTE: Selection is done in memory layout order (be careful with chunked dsets). Most likely the order of rows read will be mixed.
