Return true if the given record iterator range is continuous and the records all belong to the given table.
This tests exactly the same requiremetns needed to construct a column view, so if this test succeeds, BaseColumnView::make should as well.

Construct a BaseColumnView from an iterator range.
The iterators must dereference to a reference or const reference to a record. If the record data is not contiguous in memory, throws lsst::pex::exceptions::RuntimeError.

Return a 1-d array expression corresponding to a flag bit.
In C++, the return value is a lazy ndarray expression template that performs the bitwise & operation on every element when that element is requested. In Python, the result will be copied into a bool NumPy array.
