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

To make room for UPM C and C++ sensor code to coexist, all UPM
C++ headers have been renamed from h -> hpp. This commit contains
updates to documentation, includes, cmake collateral, examples, and
swig interface files.
* Renamed all cxx/cpp header files which contain the string
'copyright intel' from .h -> .hpp (if not already hpp).
* Replaced all references to .h with .hpp in documentation,
source files, cmake collateral, example code, and swig interface
files.
* Replaced cmake variable module_h with module_hpp.
* Intentionally left upm.h since this file currently does not
contain code (documentation only).

The driver was developed using the Veris CWLSHTA CO2 Gas sensor. The
'T' variant supports a temperature sensor, and the 'H' variant
supports a humidity sensor.
All 3 signals are provided by the device as analog 0-5Vdc, 0-10Vdc, or
4-20ma loop current outputs. For devices supporting temperature, the
valid temperature range is 10C to 50C. The humidity ranges from 0% to
100% (non-condensing). The CO2 sensor ranges from 0 to 2000 ppm.
This driver was developed using the 5Vdc outputs and the 4-20ma
outputs. For voltage outputs, your MCU must be configured for 5V
operation. In addition, you must configure the sensor (via it's
configuration switches) to output 0-5VDC only. Using any other analog
reference voltage will require the appropriate external circuitry
(such as a voltage divider) in order to interface safely with your
MCU.
In addition, the sensor can be configured for 4-20ma usage, by
specifying the correct receiver resistance (in ohms) in the
constructor. This sensor was tested with a Cooking Hacks (Libelium)
4-channel 4-20ma Arduino interface shield. For this interface, the
receiver resistance was specified as 165.0 ohms.
