 The goal of this project is to allow all hobbyists needing gcode writing to have everything they need to create the gcode their projects requires. The secondary goal is to get this project basically wholesale assumed into vpype proper. The writer is so open and modular that it can write everything from svg to json to gcode, the hope was to get this sort of thing added to vpype.
 
 # Philosophy
-Breaking changes are fine. Anything that will make this code more likely to end up in vpype properly and this particular library getting deprecated will be highly likley to be done.

+`gwrite` uses `.format()` encoding which means that data elements must be encapsulated in `{}` brackets. This provides a particular syntax token which differs from between elements.
 For example every element except `layer_join` and `segment_join` accepts the value of `index`. You would encode that in the text as `{index:d}` the d denotes an integer value. If you need to have a `{` value in your text you would encode that as `{{` likewise you would encode a `}` as `}}`.
 - `layer_start`: Accepts `index` the current layer number.
 - `layer_end`: Accepts `index` the current layer number.
