* Create directory of source and compilation files for a new boundary condition
  <boundaryConditionName> (dir)
  - .C and .H source files
  - Make (dir)
    - files
    - options
  Compiles a library named lib<boundaryConditionName>.so in \$FOAM_USER_LIBBIN:

<base> conditions:
-f | -fixedValue    | fixedValue
-m | -mixed         | mixed
