First pass of load files through an interface (to allow loading from memory, zip file etc). So instead of posix fopen/fread, using CommonFileIOInterface. A fileIO plugin can override custom file IO operations. As a small test, load files from a zipfile in memory. Default fileIO implementation is in examples/Utils/b3BulletDefaultFileIO.h Affects URDF, SDF, MJCF, Wavefront OBJ, STL, DAE, images. 2018-10-09 04:27:08 +00:00			`#ifndef COMMON_FILE_IO_INTERFACE_H`

example for fileIOPlugin.py loading SDF and its assets from a single zipfile, also show how to disable file caching (used in the fileIOPlugin) 2018-11-17 22:11:01 +00:00			`virtual void enableFileCaching(bool enable) = 0;`
