Searches a given project directory for references to a given file.
usage: npm i then npm start and follow the prompts.
Rather than using an app entry point to begin the search, this performs a brute-force search of all files in the project directory that match allowedExtensions within src/index.ts.
An inventory of resolved vs unresolved dependencies can be seen by calling npm start -- --debug
If searching for template files, pass -t or --template followed by the template engine. Currently only rendr views and templates are supported.
