00013  * @brief <strong>TWI_Master</strong> is used for interacting with different libraries of I2C sensors, which I wrote.
00014  * This library has been inspired by the <a href="https://github.com/adafruit/Adafruit_Sensor">Adafruit Sensor-Library</a> 
00015  * and the <a href="https://github.com/jrowberg/i2cdevlib/">I2Cdevlib</a> by jrowberg.
00016  * \n\n
00017  * It is not an I2C driver, since the existing I2C functions are used and new things, such as masking and individual 
00018  * bit changes, are built in around them.
