Code improvements

[MatthewScholefield]

This brings in the following changes:

• Code reformat
  • Using tabs instead of spaces
  • else clauses begin on same line as bracket
• Import normalization
• Minor idiomatic improvements (ie. using references rather than pointers)

The commits detail more specific changes. Please test to ensure this PR won't have any behavioral differences.

@Wolfgange3311999 As we talked before, it's good to have our standard format and use tab instead of space. However, this tab is too long. It seems 8 space long instead of 4. Please, fix that.

[MatthewScholefield]

@jdorleans The tab size is depends on the editor or viewer you are using. For GitHub you can change it like this.

OK, I've added the last changes so this is now ready. The license will be added in a separate commit.

@jdorleans lgty?

@Wolfgange3311999 what are the TimeOne changes? Have you just updated the lib?

[MatthewScholefield]

@jdorleans Yes, I updated the TimerOne library to a different fork that is better maintained and uses an MIT license rather than GPL. This is because there was talk of making the enclosure code MIT licensed although that is in no way final.

Let's merge this!
