* Add common tools for spell check
* Updates from further iteration
* Review feedback: Add check for git as well
* Review feedback * Use common approach to resolving base branch name * Eliminate default base branch "master" as this will be changed later, providing no default and using a mandatory parameter means a dev must provide the value * Check for existence of $CspellConfigPath * No need to Set-Location if run from the root of the repo (most common scenario) * -join
* Review feedback: Rename TargetRef -> TargetBranch, add SourceBranch, Add reference to spelling docs, exit 0, Rename to check-spelling-in-changed-files.ps1,
