Major refactor and API changes

- Updated `.gitignore` file
- Updated `CMakeLists.txt` to build static exectuable
- Changed some `Doxyfile` configurations to build more robust and complete documentation (WIP)
- Changed how `remote` works to better reflect `git`'s API (WIP)
- Changed how error handling works
- Improved `bin/compile.sh` script
- Improved `bin/lines.sh` script (kinda)
- Removed some instances of `fmt` in favor of `std` string functions
- Restructed style for better readibility

+	By default, packages are stored in a global directory and linked to the project
+	where the tool is executed. Use the `--jobs` option to install packages in 
+	parallel. Specify which remote source to use by passing the `--remote` option.
+	By default, the first remote source will by used. Alternatively, if the
+	`--use-remote=false` option is passed, then the tool will only attempt to fetch the
+	package from cache. Use the `--use-cache=false` option to fetch package only from

+
+	To install a package to a local project only, use the `--local-only` option.
