initial commit
First refacton on data structures used by the scanner

created a new Scan_points class and a test driver
added makefile to repo
successful build on first data structure dev test
successful unit test on creating the initial Scan constructor
full construtor and destructor implemented
data structures functional.

Moving on to implement scanner interface.
compiling with basic servo control logic
compiles in Arduino IDE...won't compile offline

too many library dependencies to compile against original unit
test.  Ready to test on Arduino hardware.
final changes for 6/1
minor edits
corrected Scanner.h
updated Scanner.cpp
updated the example
Examples work
working copy with changes for JSON lib compaibility

changed .data() method to a non-const char* so it would
interface as the JSON string to the JSON lib
Added a data member to the Scanner class

Added a data member to the scanner class to track the number of
test points the scanner was constructed with. This data is then
used to calculate the size of the data buffer for the JSON string
that returns measurements which can be accessed with
    .data_size()
method.
updated description in .h file
