* lv.el (lv-wnd): New variable.
(lv-window): New defun to get a window similar in properties to Echo Area.
(lv-message): New defun, a replacement for `message', that writes to `lv-window'.
* hydra.el (hydra-lv): New defcustom. If nil, use the Echo Area,
otherwise, use LV.
(hydra-disable): Add optional arg KILL-LV.
(hydra--message): New defun to dispatch on `hydra-lv'.
(hydra--make-defun): Prematurely disable with LV only for blue heads,
since regenerating LV window would cause screen tearing. No need for
timeouts between `message' when using LV. HINT argument is now a
function symbol that returns a string, instead of a plain string.
(defhydra): Generate a new defun with name `NAME/hint'.
* Makefile: Load lv.
* hydra-test.el: Update all tests.
* README.md: Update.
* hydra.el (hydra-base-map): Model after `universal-argument-map'; all
Hydra keymaps will inherit from this one.
(hydra-curr-map): Current Hydra keymap. This is necessary for
e.g. `hydra--digit-argument' to return to the orignial keymap.
(hydra--universal-argument): New function.
(hydra--digit-argument): New function.
(hydra--negative-argument): New function.
(hydra--hint): Fix dangling `body-color'.
(defhydra): keymap will inherit `hydra-base-map'.
`hydra-current-map' will be set by red heads. In red heads, make the
function call after `set-transient-map' so that e.g. "Beginning of
buffer" error will not exit the Hydra.
* hydra-test.el: Update tests.
Fixes#13.
