Fast cross-correlation searches a 2D/3D density map for a template.

Parameters

*p	the Fourier transformed image.
*ptemp	the Fourier transformed template to be searched for.
view	view.
*kernel	interpolation kernel.
hires	high resolution limit.
lores	low resolution limit.
*pmask	mask for cross-correlation (ignored if NULL).

Returns

double correlation coefficient.

The template is rotated to the view and cross-correlated to find
a set of high-scoring fits.
The views must be calculated externally to allow for custom sets.
The best view is returned in the image view record.
