Reorganize source files (#41)
* Remove unused device and stamp from swipe_impl
* Use constants for regex patterns
* Compile regex outside of buffer function to avoid runtime hiccup
* Optimize reading of config file
* Revert "Optimize reading of config file"
This reverts commit 88b85d3941.
* Improve tokenizing of config file
* Make sentence string static
* Improve README; change default threshold to 20.0
* Add a flag for gesture begin to ignore unneeded update/end
* Pre-compute for square of threshold and scale to lessen computation
* Compare fingers string with only one digit
* Use fgets_unlocked for faster input stream reading
* Don't buffer error stream
* Set some variables to static
* Catch dash symbol before event, remove trimming
* Use const char* for conf_filename
* Fix error in printing help
* Add some test scripts
* Add service module
* Add gesture module
* Add util module
* Add index files
* Decouple header files
* Add licenses in headers
* Move files to lib
* Modify install script
* Update install script
