public member BMI160.getMotionDetectionThreshold() fails compile with 'is private within this context'

[awardblvr]

Using getMotionDetectionThreshold() thusly:

    BMI160.begin(BMI160GenClass::I2C_MODE, I2C_ADDR_ACCEL_BMI160, ACCEL_INT_1_PIN);
   ...
    Serial.print(", MotionDetectionThreshold:");
    Serial.print(BMI160.getMotionDetectionThreshold());
   ...
    Serial.println();

I get

I found by editing the copyrighted file .../Arduino/libraries/BMI160-Arduino/CurieIMU.h
and moving those function declarations from the private: section to the public: section, resolves the issue... (But, they are already public in BMI160.h! ) So.. Not sure how the inheritance thing is working on this.. But it NEEDS to be fixed. (please)
