implementing and testing simple key map/match module
implementing map-sequence tests to switch to normal when mapped to escape
only popping buffer in insert mode
insert mode sequence mapping working, but related map tests fail due to interface change
fixing map tests
rearranging
fixing map test result output
fixing all tests
only logging if debug env variable is set
more meaningful threshold
more specific debug variable
fixing logging line only in debug mode
fixing off by one ! error
adding tests for non matched sequence
sequence mapping implemented and tested, included stringify-key to use it to match key combinations
map module handles key combinations
some refactoring of match making (separated out insert mode)
refactored out insert-mode
no longer exposing normal/insert mode functions on vim
adding documentation to map module and making API more consistent (only work with string or array of chars)
