Re-sample the griddedData on the VisBuffer (a.k.a gridding).

In this class, these just call the private templated version. The first variant grids onto a double precision grid while the second one does it on a single precision grid.

Note that the following calls allow using any CFStore object for gridding while de-gridding uses the internal convFuncStore_p object. virtual void DataToGrid(casacore::Array<casacore::DComplex>& griddedData, VBStore& vbs, casacore::Matrix<casacore::Double>& sumwt, const casacore::Bool& dopsf, CFStore& cfs) {DataToGridImpl_p(griddedData, vbs, sumwt,dopsf,cfs);}

Internal methods to address a 4D array.

These should ulimately moved to a Array4D class in CASACore

This is called less frequently. Currently once per VisBuffer inline void cacheAxisIncrements(const casacore::Vector<casacore::Int>& n, casacore::Vector<casacore::Int>& inc) {inc.resize(4);inc[0]=1, inc[1]=inc[0]*n[0], inc[2]=inc[1]*n[1], inc[3]=inc[2]*n[2];(void)n[3];}

The following method is also called from the inner loop, but does not use CASA casacore::Vector (which are not thread safe, I (SB) am told).

return store[iPos[0] + iPos[1]*inc[1] + iPos[2]*inc[2] +iPos[3]*inc[3]];

This rotates the convolution function by rotating the co-ordinate system.

For the accuracies already required for EVLA and ALMA, this is not useful. Leaving it hear for now....
