Fundamentally flawed version of DTW

This flawed version of DTW solves for shift increments r instead of
shifts u. When the increments are accumulated, the resulting shifts u
are incorrect for some trivial test cases.
Delete flawed R version of dynamic time warping.
New R version of dynamic warping.

This version solves for shifts u(t), but provides fine sampling of
strains r = u'(t) by solving for shifts on a coarse grid obtained by
subsampling the t axis.
