When the changed file was not found, there was no information from the cli which would let me know this. Because of that, an incorrect file path would be silently responded to with `"Replacing from with to"`.
* Added support for passing Regex into CLI
This will allow for passing the `from`/`to` parameters as regex in the format `\match\g` through the CLI. If pattern does not match a Regex it will fall back to passing through as a `String`.
* - Fixed style inconsistencies
- Added -isRegex parameter to explicitly state ‘from’ parameter is a regex
- Removed regex support from ‘to’ parameter
* Replaced -isRegex with —isRegex and moved to the end of the param list
* Added line and sample syntax for CLI in README
