Start of some speeds up to soder.m.
Added the start of a test for soder.m.
test_soder.m works now.
Added a simple function for timing the Octave soder.m
Added a Soderkvist numpy function.

This is a highly vectorized version of the soder.m. It gives ~30X speed up to
the current Octave version. Computation for 60000 frames takes about 850 ms on
my machine as opposed to 25 seconds with Octave. The code is not producing the
correct results yet.
test_markers.py now passes.
Removed comment.
Added octave wrapping to inertial compensation and inverse dynamics.

This adds a dependency to oct2py and octave and methods to the DFlowData and
WalkingData classes that enable use of the octave files for inerital
compensation and 2D inverse dynamics. Filtering was also added to DFlowData.
The time delays from the accelerometers are now delt with. Filtering was added
to the GRF landmark detection.

Integrate inertial compensation into DFlowData and 2D inverse dynamics into WalkingData.
