- oolin now can handle matrices: oolin(C) creates oofun that returns numpy.dot(C, inp_array); oolin(C, d) yields oofun that returns numpy.dot(C, x) + d. See updated oolin example.
- add fixed variables handling for oovars. Now you can declare v.fixed = True or just v = oovar(..., fixed = True). So all oofuns that recursively depend on fixed oovars only will be calculated only once, and derivatives will be all-zero (hence no calculations will be required for those parts of code that depend on fixed oofuns only). In future it will be good to have inner fixed coords for oovars, like this: v.fixed = [0, 1, 15] (i.e. positions of fixed coords inside the oovar). See the fixed oovars example.
