Cleanup of UPM C++ examples. Switched from heap allocation to
stack allocation when possible. This simplifies the samples since it
removes the need for explicit memory management. A script was used to
identify and replace pointer use. To simplify the replace script, I
re-formatted the C++ examples using the UPM .clang-format file.
Unfortuantely this changes the look of the UPM C++ examples to a large
degree. However, examples will now have a standard look/feel and
uniform formatting.
* Ran clang-format w/provided UPM .clang-format file
* Removed new's/delete's whenever possible (left those in interface
examples)
* Added IIO sensor library implementation of callback void* arg
* Converted all sleeps to upm defined delays (added header when
necessary)
* Scrubbed CXX example includes

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.

This library adds support for both the BMP280 and BME280 sesnors from
Bosch. The BME is virtually identical to the BMP280 aside from some
slight register changes and adding support for a humidity sensor.
The BMP280 is an absolute barometric pressure sensor especially
designed for mobile applications. The sensor module is housed in an
extremely compact 8-pin metal-lid LGA package with a footprint of only
2.0 × 2.5 mm2 and 0.95 mm package height. Its small dimensions and its
low power consumption of 2.7 μA @1Hz allow the implementation in
battery driven devices such as mobile phones, GPS modules or watches.
The BME280 is as combined digital humidity, pressure and temperature
sensor based on proven sensing principles. The sensor module is housed
in an extremely compact metal-lid LGA package with a footprint of only
2.5 × 2.5 mm2 with a height of 0.93 mm. Its small dimensions and its
low power consumption allow the implementation in battery driven
devices such as handsets, GPS modules or watches. The BME280 is
register and performance compatible to the Bosch Sensortec BMP280
digital pressure sensor
These drivers support both I2C and SPI operation.
When using SPI on an Edison with the arduino breakout board, you
must specify a CS of -1 to the constructor, and connect the chip's
CS pin to arduino pin 10.
