*important* Jacobian computation: outputs matrix of NANs if central difference cannot be computed
	modified:   src/Field.C
Bug fixed: phys_to_cell() returns the fisrt cell of the next line when querying for physical values of the border points
Corrected Jacobian computation for curvilinear grids.  Increase matrix inverse precision to double
Increase 4x4 matrix inverse precision to double
