New:
---

Flow field initialization with given (e.g. measured) profiles. Profile data
for u-,v-velocity components + respective heights are given with new
inipar-parameters u_profile, v_profile, and uv_heights. Final profiles are
calculated from these given profiles by linear interpolation.
(check_parameters, header, init_3d_model, modules, parin)

Changed:


ug,vg replaced by u_init,v_init as the Dirichlet top boundary condition
(boundary_conds)

dirichlet_0 conditions moved from init_3d_model to
check_parameters (check_parameters, init_3d_model)

Errors:


bugfix: dirichlet_0 conditions moved from init_3d_model to
check_parameters (check_parameters, init_3d_model)
