Add copyright to .cs files and assemblies to enable open sourcing

[al-fisher]

Broken rules:

Before migrating this toolkit to BHoM org the copyright statements need to be correct

Suggestions to restore compliance:

As per snippet from open sourcing guidance in wiki - see below. Licence is already in place and correct from template, but copyrights need reviewing.

Licencing and copyright

• Ensure repository has valid licence file.
  BHoM defaults to LGPL v3 https://github.com/BHoM/BHoM/blob/master/LICENSE.
  Repositories can be licenced differently, but by exception only and through agreement with BHoM Organisation Administrators. And would then require modifications to the repo's copyright headers in every code file.
• All code files must have a valid BHoM copyright header compatible with licencing (see point above) See here for the default https://github.com/BHoM/BHoM/blob/master/COPYRIGHT_HEADER.txt
• Assembly information and the included copyright must also conform to BHoM standards.
  Such as [assembly: AssemblyCopyright("Copyright © https://github.com/BHoM")]

Depending on the number of files that need copyright adding - BHoMBot can help with this if needed :smile:

@FraserGreenroyd thanks only a few files. Another question - do the csproj files need switching to the new format to avoid down-the-line issues?

I noted some failing project compliance issues elsewhere which I am guessing are due to use of the old csproj format? https://github.com/BuroHappoldEngineering/Defra_Toolkit/pull/2

@rolyhudson looks like those errors will exist regardless of project format, as it's information about the references that are missing :smile:

[FraserGreenroyd]

That said, upgrading to the new format is being recommended if you're up for the new format!
