v1.0.0-alpha.3

Added a radio group calibration function that checks what groups are sending data.

v1.0.0-alpha.2

Started to re-write the whole shell due to unorganised and inefficient code.
Bugs are still here in this version but will be fixed in newer ones.

v1.0.0-alpha.1

Removed useless shell start info.
Added some commands.
Still no useful functionality.
This issue is still not fixed.

v1.0.0-alpha (The very first release of microbit-shell)

This version of microbit-shell involves the essential functions of the program.
It has some commands, like: help, info, about and reset.
This is a very early version of the shell and may be very buggy.
It is not to be used fully because it is pretty useless.
