Singleton for reading the configuration file required for your program.
The `settings.conf` file:
## Quick start
```conf
Such a line will not be read
value1 = This is the full value
value2 = "Take the value in quotation marks"
value3 = 'Or take in apostrophes'
value4 => You can also comment // Another separator and comment
value5 => 'So you can also comment' # Yeah!
value6 => 'And you can even do that!' ; He-he;)
value7 = 1234567890 # decimal value
value8 => 12345.67890 ; float value
value9 => You can use large margins
value10 = // But a line without a value will not be read
value11 = //path # not working
value12 = "//path" // nice way (or '//path')
```
The `settings.conf` file (see the [tests](tests/)):
