This driver has been rewritten from scratch.
See docs/apichanges.md for a list of API compatibility changes
compared to the original driver.

The sainsmartks driver has been reimplemented in it's own, new C/C++
library: lcdks (LCD Keypad Shield).
In addition, support for an optional backlight GPIO was added.
This was tested with the SainsmartKS and DFRobot LCD Keypad Shields.

Some private methods (relating to calibration/compensation) are no
longer exposed. In addition, the driver auto-detects the chip (BMP280
or BME280) and acts accordingly, rather than requiring the
specification of a chip id in the ctor.
The getHumidity() method no longer accepts an arguement representing
pressure at sea level. A new method is provided to specify this.

The API has been changed in some cases - see the apichanges.md
document.
In addition, this driver uses a new upm_vectortypes.i SWIG interface
file to provide a mechanism for methods that return a vector of floats
and ints instead of a pointer to an array.
This works much nicer than C array pointers, and results in Python/JS/Java
code that looks much more "natural" to the language in use.
The Python, JS, and Java examples have been changed to use these
methods. Support for the "old" C-style pointer methods are still
provided for backward compatibility with existing code.
As an example - to retrieve the x, y, and z data for Euler Angles from
the bno055, the original python code would look something like:
...
x = sensorObj.new_floatp()
y = sensorObj.new_floatp()
z = sensorObj.new_floatp()
...
sensor.getEulerAngles(x, y, z)
...
print("Euler: Heading:", sensorObj.floatp_value(x), end=' ')
print(" Roll:", sensorObj.floatp_value(y), end=' ')
...
Now the equivalent code is simply:
floatData = sensor.getEulerAngles()
print("Euler: Heading:", floatData[0], ...
print(" Roll:", floatData[1], end=' ')
...
Additionally, interrupt handling for Java is now implemented
completely in the C++ header file now rather than the .cxx file, so no
special SWIG processing is required anymore. See Issue #518 .

Previously, the C++ and C versions of this driver were separate. Now
the C++ implementation wraps the C implementation.
In addition, the C++ init() function has been deprecated. It
currently does nothing, and examples have been modified to remove it's
calls. This function will be removed in a separate release.
The examples have been further modified to update all detected devices
and print their respective temperatures, instead of only reporting the
on the first device detected.
