ECP 1: Establish time-to-solution for ABL

[spdomin]

Activities:

1. Documentation of the ABL model implementation in NaluDoc.
2. Implementation of appropriate wall boundary conditions for energy and momentum transport.
3. Prototype STK_transfer of inflow boundary condition from the ABL to a subsequent simulation in which “velocity_bc” is interpolated in space and time for use in the inflow bc.
4. Testing, at available scales, ABL with solver and general algorithmic costs.
