Logchecker

- In function `parseResults()`, better detection of `json` files.
- When the name had a dot `.` in its name, parsing was not being performed. Is solved now.

- Parameter `-json` with default = yes.
- Updates on when platform is windows (equal to win64 or win32), to handle with paths correctly:
- In function `readLog()`: update of listContent.
- In function `main()`: condition to replace `/` in templateFolder

- The folder of the templates can now be specified by the parameter `--templateFolder`. The default is `TemplatesTextFSM/`.
- The file `--csvTemplate` is now optional. If omitted, then all the templates under the folder `--templateFolder` will be considered for parsing.
- Templates can be of type `textFSM` or `ttp`. To choose, use the parameter `-te/--templateEngine`.
- Be sure to point to the correct folder of templates, when changing the engine.

- ReWrite of functions `readTemplate()` , `readLog()` and `parseResults()`.

- Starting major version `2.0.0`.
- ReWrite of function `constructExcel()`
- If data is empty, because parsing detected nothing, tab color is now blue. This will help identify easily when parsing is not working.
- Nex `index` tab implemented, with hyperlinks to all sheets.
