Create a filter index of a track for "bad" points with a
combination of speed, distance and angle tests.

Access and manipulate spatial tracking data, with straightforward
coercion from and to other formats. Filter for speed and create time spent
maps from tracking data. There are coercion methods to convert between 'trip'
and 'ltraj' from 'adehabitatLT', and between 'trip' and 'psp' and 'ppp' from
'spatstat'. Trip objects can be created from raw or grouped data frames, and
from types in the 'sp', sf', 'amt', 'trackeR', 'mousetrap', and other packages,
