COMP: adjust build order

- blockMesh <- extrudeModel <- dynamicMesh

COMP: bad constructor in searchableSphere

- used brace initializer instead of bracket initializer, which
  triggered component-wise construction instead of copy/move
  construction (gcc 4.8)

STYLE: use uint8_t instead of relying on definition of 'direction'
