[R-pkgs] trip package: version 1.1-2

[Michael Sumner]

Hello,

A long overdue update to the 'trip' package is now on CRAN.

o New function forceConstraints() to impose the common problems found in 
track data of duplicated records, and duplicated time stamps.
o Bug fix to speedfilter() which would never finish for trips of 3 
locations.
o Clean up of trip methods to fix a bug that caused R CMD check to fail 
in 2.8.0.

Thanks to all who provide feedback for problems and ideas for improvements.

Regards,
Mike.
