Spline interpolation

[Stephen Gatesy]

For tracking unmarked or poorly marked features, it would be great to only manually track a subset of frames and then have the 3-D points interpolated by a spline as in Maya and other animation programs. Such "single-point rotoscoping" is by no means ideal and does not make use of all the powerful auto-tracking features, but we have a need for it.

Ideally, the splines would be represented in the translation plot windows with only the "keyframes" shown as points. Users could then add or delete frames as needed to get a better alignment without having to do every frame (particularly when a point is static for long periods of time).

fixes #12 : Added interpolation - Removed polyfit optimization from detection methods - Reassigned markerstatus - Changed format to 0.2 - added delete for several dialogs which were not cleaned up - Fixed a bug in which the marker dialog was not assigned the correct marker id
