.command_which(cmd, only_path = false) ⇒ Object
Cross-platform way of finding an executable in the $PATH.
Idea taken from bit.ly/qDaTbY, if only_path is true, only the path is returned (not the path and command)

.device_list ⇒ Object
Currently only functions on Mac.
Returns a list of system camera devices in a format suitable to display to the user.

.git_config_color_always? ⇒ Boolean
Is ‘git config color.ui` set to ’always’?
Due to a bug in the ruby-git library, git config for color.ui cannot be set to ‘always’ or it won’t read properly.
This helper method let’s us check for that error condition so we can alert the user in the CLI tool.
