% input:  struct array of mocap structs, with a .syncpoint field. 
%         The syncpoint is given in frames, and may be obtained from the
%         mcarraySyncWindowed function
%
% output: struct array of mocap structs. Aligned according to the
%         syncpoint field, and cut by the latest start and earliest 
%         stop time across all recordings.
