Potential optical flow, AR pipeline

in this new folder I put every script that leads to AR parameters from
video data.
I recommend opening AR_pipeline_help.m to see the order of steps and
then copying that script directly into the command window. Then you can
verify that all the intermediate variables are at least the right
dimensions and such on the list of active variables. Let me know what
you think. FYI, rconv2sep and upConv are from matlabVisTools.
estimate_flow_interface and load_of_method are from the optical flow
code
