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)

Bugfixes

(none)

Initial Alpha

Moved to alpha

Improvements to read more versatile formats

Improvements

• Tests include a sample-set of gcode files from varying CAM software and authors.
• lsenv in deployment script.
• added GCodeLineNumber and GCodeProgramName (in response to #5).
• GCodeCancelCannedCycle sets machine mode to None, and is run first in list of motion gcodes.
• Error message for unsupported gcodes is more helpful / relevant.
• Optional whitespace in Word, (eg: X-1.2 and X -1.2 are now both valid)

Bugfixes

• #5 Line number in program

0.1.2

Changes to accommodate implementation of grbl-stream

Improvements

• added NullMachine, NullState, and NullMode (not assuming any machine state)
• Block length is the number of gcodes + 1 if modal parameters exists

Bugfixes

• % enclosed lines are considered to be macros when parsing
• added axes ABCXYZ as valid parameters for G10 (eg: G10 L20 X0 Y0 Z0)
