Lattice fields

The module Fields include simple routines to define a few typical fields. Fields are simple CuArray types with special memory layout. A field always has an associated elemental type (i.e. for gauge fields SU3, for scalar fields Float64). We have:

scalar fields: One elemental type in each spacetime point.
vector field: One elemental type at each spacetime point and direction.
N scalar fields: N elemental types at each spacetime point.

Fields can have naturaL indexing, where the memory layout follows the point-in-block and block indices (see SpaceParm). Fields can also have lexicographic indexing, where points are labelled by a D-dimensional index (see scalar_field_point).
