Minor update

Still v0.9.

Minor bug fixes.
Removed dependency on ssh/putty when working through RSclient
Simplified remote work.
Moved all examples to where they belong, stated that they are "as is" and may be not up to date.
Updated/simplified getting started.

Next:
Considering swithing to other R class system (R6 or R5) mimicking C++ syntax:
- after prototyping in R the code could easily be changed to C++ and called using RCPP

More distant goals:
- swithing to autogen 
- updating to v0.9.1
- some version to master (needs final decision on class system and syntax)

Note:
-the sensor command interface was used privatately before it was even in specs so it may not follow the guidelines yet
