Cycle Setting plugin for Sublime Text 2.
Copyright 2012 Jesse McCarthy <http://jessemccarthy.net/>.

Adds a command that can be called from a key binding to toggle or
cycle through values for a non-boolean setting.

There are 'set_setting' and 'toggle_setting' commands built in to
Sublime Text 2 that can be called from key bindings.  But, as far as I
can tell, 'toggle_setting' only works for boolean settings, such as
'word_wrap'.

This plugin adds a 'cycle_setting' command that can cycle through
several values for a setting, or toggle between two for a non-boolean
setting.  An example setting is 'draw_white_space'.  'cycle_setting'
can be used to cycle through the values 'none', 'selection', and
'all', or toggle between two, such as 'none' and 'all'.

Currently this changes the setting for the current buffer, like the
built in 'set_setting' and 'toggle_setting'.


USAGE:

See the sample sublime-keymap file for an example.

Set 'command' to 'cycle_setting'.

Set 'args.setting' to the desired setting.

Set 'args.options' to a list of the setting values you want to cycle
through.


TO DO:

* Figure out a way to skip this code if a built in command of the same
* name, and especially with the same features, is introduced.

* Figure out if some settings have enumerated values that I can read
* in the plugin, in case the user would just like to cycle through all
* available options.
