Laex 3ae4ef8956 Some changes
[*] Rename files of:
- Calib3d.pas in calib3d_s.pas
- Tracking.pas in tracking_s.pas
To ensure conformity with the file names OpenCV library
[!] Modules used in the project without the inclusion of relative paths. Added instructions on how to add the module search path (see readme_en.txt)
[+] Added an example Posit (cvReleasePOSITObject, cvPOSIT and others) (thanks to Frans van Daalen (CLubfitter73))
