               ImmediateHeaderProcessor

An base for processors doing simple FITS manipulations to the primary FITS header.

To define these, override ``_isProcessed(self, srcName, hdr)`` and ``_changeHeader(self, hdr)``.

``_changeHeader`` can change the pyfits header ``hdr`` in place. It will then be replaced on the actual file.

For complex operations, it is probably advisable to use ``HeaderProcessor`` which gives you a two-step process of first having the detached headers that you can check before applying them.
