0.2.1

Improvements

pygcode-norm script:

Added "Final Machine Actions:"

Final Machine Actions:
  standardize what's done at the end of a gcode program.

  --zero_xy, -zxy       On completion, move straight up to
                        rapid_safety_height, then across to X0 Y0.
  --zero_z, -zz         On completion, move down to Z0 (done after zero_xy, if
                        set).
  --rapid_safety_height RAPID_SAFETY_HEIGHT, -rsh RAPID_SAFETY_HEIGHT
                        Z value to move to before traversing workpiece (if not
                        set, max value will be attempted).
  --spindle_off, -so    On completion, turn spindle off.

Added ability to remove all codes & parameters that cannot be parsed.

  --rm_invalid_modal, -rmim
                        Simply remove everything that isn't understood. Use
                        with caution.

Library Improvements

• Machine.abs2work(<Position>) and Machine.work2abs(<Position>) position
  converters, apply machine's offset to the given position without effecting
  machine's current position.
• Machine.clean_block(<Block>) removes content from a block that's not parsable (use with caution)
• Machine.ignore_invalid_modal bool class parameter, if set, will continue on merrily while ignoring
  anything not parsable (similarly to clean_block)
• deployment version category validation in setup.py (ie: alpha, beta, and so on)
