Detailed Description

Reader class for the position file.

Each call to read() gives the next position entry from the file. When atEnd() returns true, all positions have been read.

Binary file format description 

Header:
  "SNWPOS"<version>

Entries, can be one of:

 * Change tool. All position entries following this one belongs to the given tool
     <type=2><size><toolUid>

 * Position. integer-format tool id are appended.
    <type=1><size><timestamp><position><int toolid>

 * Position. Requires change tool to have been called.
    <type=3><size><timestamp><position>

 The position field is <position> = <thetaXY><thetaZ><phi><x><y><z>
 Where the parameters are found from a matrix using the class CGFrame.
