Update SummariseAll.R

Added acf extraction description
acf extraction #1

added in acf extraction code, but issues with subsequent rbind summary
in main function, so aiming to rework to read in traj then use separate
functions to do parameter summary and acf extractions
Version 1 commit

Major rework of code to create subfunctions to do the import and
extraction of parameters and acf values, wrapped in summarisePaths
function, which tidies up at the end, adding treatment factor and
returning list for further analysis
Merge remote-tracking branch 'origin/AddACF'
