43 expand load command to compute multiple sweep parameters (#44)

* Added sweep methods

* Removed cache

* Refactoring to put a strategy into redis, and then a queue of runs to sweep

* Refactoring operations to be within a thread to scale up backtesting sweeps

* fixed the build

* Fix ubuntu build

* Fixing the header references for explicit include

* Updating tests and refactoring operations

* further refactoring, renaming methods

 ### Headers folder (./source/include)
-Header files are saved within ./source/include
+Header-only headers in include/ are globally available and source/*.cpp is globbed automatically.
 
 ### Pragma once
-Headers should use `#pragma once` directive. It's non-standard but widely supported preprocessor directive in C and C++. It's used as an include guard to prevent multiple inclusions of the same header file.
