First of all, thanks for contributing!

A few things:

1. There was a lot of whitespace change in your BrightScriptFormatter.ts file. Can you update the file to match the formatting of this project so that only the actual code differences show up in the git diff? This project uses 4 spaces per tab, not 2. My guess is that you have that setting overridden somewhere in your editor? I just pushed a new commit to master that with some new formatting settings in the vscode config that will help enforce this at development time in the future.
2. Can you add some more tests? I would like to see a few more complex statements be tested. (I put the proper amount of spaces in my markdown, but it doesn't look like it's rendering them.) See my other tests for examples. I usually just write my program using the default formatting options, write the code the way it is supposed to be formatted, and then format it. If it came out the same way, then the formatter works.
   • "#if isDebug\n doSomething()\n#end if"
   • "#if isDebug\n doSomething()\n#else\n doSomethingElse"
   • "#if isDebug\n doSomething()\n#else if isPartialDebug\n doSomethingElse()\n#else\n doFinalThing()\n#end if"
     -"#if isDebug\n if true then\n doSomething()\n end if\n#end if"
   • "if true then\n #if isDebug\n doSomething()\n #end if"

Thanks for your comments and remarks.
Starting to fix those issues.

I fixed the whitespace issues and added tests for conditional compile blocks.

@TwitchBronBron, can you please review the request?

Thanks

Done. There were still a ton of whitespace issues in the main file (i.e. they were still indented with 2 spaces instead of 4), but I'll just fix them. Thanks for your contribution.

Strange...
My default indentation is 4 spaces in all projects. Maybe is a formatter issue.
I'll check after the merge.
