[WIP] Align laminar LFP to L5 features

[blakecaldwell]

Adding the following to hnn.cfg will enable LFP recording.

[run]
laminarlfp = 1

Documentation in code on calculating contact positions relative to L5 features

  scheme for obtaining results that are analogous to laminar recordings:

  Laminar probe  | L5 Pyr. | Location in HNN  | Label
  -----------------------------------------------------------------------
   |
   |
  --- contact 1             1466 + 2*spacing   first LFP electrode
   |
  --- contact 2             1466 + spacing     top of CSD plot
   |
  --- contact 3      |      1466               top of L5 apical dendrite
   |                 |
   ~                 ~
   ~                 ~
   |                 |
  ~~~ contact N-4   /_\     ~177.5             (approx) center of L5 soma
   |                 |
  --- contact N-3    |
   |                 |
  --- contact N-2    |      -72                bottom of L5 basal dedrite
   |
  --- contact N-1           -72 - spacing      bottom of CSD plot
   |
  --- contact N             -72 - 2*spacing    last LFP electrode

If you have spent some effort in figuring this out, perhaps it could be worth porting this to mne-neuron/hnn-core -- in a cleaner way. I know it doesn't feel like it's worth the effort but keeping things clean will pay off eventually I promise :)
