`HorzMesh` structure does not support non-periodic meshes

[andrewdnolan]

Limitations Include:

• When edgesOnVertex contains zeros (i.e. the vertex is along a culled boundary) an BoundsError is raised in the signIndexField! method, which tries to index arrays at 0. For example:

  ERROR: BoundsError: attempt to access 2×555 Matrix{Int32} at index [1, 0]
  Stacktrace:

     @ ./essentials.jl:14 [inlined]

• Horizontal mesh structures do not yet have *Mask arrays (i.e. edgeMask) arrays, meaning horizontal boundary conditions (i.e. no slip) will not be correctly applied.
