evonneng a498a6cc64 Standardized logging code to all global var; writers now accessible from all files (#62)
* added skeleton for terminal logger

* done skeleton terminal writer logic... todo: actual calls to the write classes

* moved lambda to top function

* added logic to support timing

* prettier printing

* prettier printing

* lint

* separated out timing and other stats variables. printing in dict format

* keeping logging history and wiping rest

* updated logic to calculate total times instead of average times

* made stats tracker configurable

* moved stats tracker and profiler to own class file; implemented basic functionality for profiler

* lint removing duplicate function

* update readme; moved around config variables

* profiler prints on sig kill

* merge

* standardized all logging to global variables
