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
