Version 0.3.4

Final tweaks to BB Blue production image, mainly letting example programs run as root user without sudo.

• add setuid on example install so 'sudo' is not needed
• rc_balance will calibrate gyro automatically if needed
• add ldconfig to deb package scripts

SHA1: 628d329

Version 0.3.3

Release for BB Blue image

• update project template for new api
• warn user if not running as root
• remove touch from makefiles

Version 0.3.2

• Fix DSM driving in balance
• Update documentation source comments
• Smoother install with new debconf question

Version 0.3.1

* Safely handle old and new device trees with and without postfix
* stricter whitelisting of supported boards and device trees

Version 0.3.0

Huge update, will probably break things due to renaming of library functions to have 'rc_' prefix in front of everything now for uniqueness requirement. I promise not to change things after this!

* add noninteractive mode to deb package installer
* add rc_ prefix to all functions and examples for uniqueness requirement
* fix IMU DMP priority and thread join causing segfaults in labview
* New functions rc_usleep and rc_nanosleep
* new timing functions rc_nanos_since_epoch(), rc_nanos_since_boot()
* New function rc_nanos_since_epoch() and rc_test_time example
* linear algebra functions use ARM-NEON hardware acceleration
* new examples rc_test_vectors, rc_test_polynomial, rc_benchmark_algebra
* functions to enable/disable signal handler
* rc_create_filter functions for both vectors and arrays
* new functions rc_poly_div(), rc_poly_add(), rc_poly_subtract()
* add get_random_double for accelerated double-precision float generation
* Handle new BB_BLUE red and green LEDs being controlled by the kernel
* rc_battery_monitor whitelists Black, Black Wireless, and Blue
* other minor improvements
