These are the template files used by the program. They are compiled and added to the built binary as base64 encoded strings. Feel free to add additional template files to this directory! When compiled, the name of the template file is important. What comes before the _template is what the language attribute will be to access your template. The extension which is used will be the extension for the solution file generated.
For example, the 'go' template is named go_template.go and will generate main.go each day. The 'python' template is named python_template.py and will generate python.py each day.
