fixed warning
added more locations for FTD2XX lib and include and added some windows-specific search pattern
exclude emacs on windows backup files
created 'extern' subfolder to contain e.g. external (binary) library dependencies
moved compiler specific flags to separate file; removed libusb dependency check for win32 for now (needs to be tested)
added some win32 setup instructions
Fix compiler warning: remove additional ;
Fix compiler warnings, unused variables, uninitialized variables...
Fix some compiler warnings: unused variable, unused result,
uninitialized variables
Use initialization list instead of assignment in constructor.
Add DUT initialization list, no need to set _initialized to false after
creating a new DUT instance.
extended findlibusb to search for windows lib if located in 'extern' folder
extended findftd2xx to search for library in the 'extern' folder by looking for the include (making the directory name arbitrary)
fix mistake in 'if' statement
extended readme with libusb info
changed win libusb from v0.1 to v1.0 file naming conventions
added cross-platform timer helper functions for ms sleeps; in logging, use seconds only for display due to trouble with reading ms precision timers over multiple platforms (a regression, but can be improved again in the future if needed)
modified to use w32 compatible includes
modified for libusb v1.0
added dummy impl w/ return value for api::getdaqevent()
