Add Device Base Classes

Devices:

• Add MD10C motor driver class

New Base-Classes:

• Add Transducer class for general data sources
  • Add PositionTransducer and HeadingTransducer for specific use cases
• Add PWMInterface
• Add Motor class for motors
  • Add subclass Thruster for storing position vector and angle in object

TCA9548A Multiplexer, Voltage Monitor, and Fixes

Fixes:

• Fixed PWM dead banding in BlueESC_PCA9685.
• Removed/Replaced call to bus method in ADS1x15 class.

Changes:

• Updated Python to 3.6.2 (PyCharm).
• Added support for pre-bus call functions in I2cDevice class.
  • The functions are run when any bus method is called.

Devices:

• Added voltage monitor through ADS1115, with support for voltage divider calculations.
• Added support for TCA9548A I2c multiplexer.

Update BlueESC libraries for PWM

Changes:

• Create motion package, and move blue_esc module to it (out of sensors).
• Update method names in BlueESC class, for PEP8
• Update BlueESC class name to BlueESC_I2C

New Devices:

• Add Adafruit PCA9685 library.
• Add BlueESC_PCA9685 class for PWM interfacing to BlueESC, through a PCA9685

New Sensors and Updated 'I2cDevice' Class

Sensors:

• BME280 Enivronmental Sensor
• Replace MS5837 with modified BlueRobotics version -- has more features
• Replace BNO055 with modified Adafruit version

Other Changes:

• Overridden 'read_byte_data'/'read_word_data' methods in I2cDevice with the ability to convert to signed ints and different endian

Add and Implement I2c Device Class

Changes:

• I2cDevice object has been added, to simplify smbus method calls.
• I2cDevice object has been implemented in pre-existing sensor objects.

Replace Library used for GPSRead

Fixed:

• The GPS library has been changed from the Python2 gps library to a separate Python3 gps3 library.
