This reverts commit 211fa521, reversing
changes made to 8ba56d73.

new "-log filename" option to specify log filename, e.g. for native Windows shell where we can't redirect stdout (fixes #562)

Test swig

See merge request !262

make "preallocate*" and "*nativePointer" api functions only available in C and C++ (they don't make sense in Python and Julia)

modify getJacobians, getBasisFunctions & co to take integrationPoints directly as argument (instead of integrationType)

allow for some additional blank space when reading BDF files in free field format (not sure if this is actually allowed by the BDF, but it fixes #555)

Add 'gmsh::model::mesh::getGaussPoints'

See merge request !261

Bezier coeff

See merge request !260

- document getBoundingBox when dim and tag are < 0

should be investigated further (reported by Ruth: select "3D model" for models/ElectricMachines/pmsm.geo)

- make "alignPeriodic" stuff less verbose; should this even still be called? Silently modifying the mesh
  after reading it seems like a very bad (TM) idea
