docs: Converts an absolute filepath to a relative path from a given base path
  
  For example, if the filepath is `/my/awesome/project/foo.bar`,
  and the base directory is `/my/awesome/project/`,
  then this function should return `foo.bar`.
  
  path.relative() does something similar, but it requires a baseDir (`from` argument).
  This function makes it optional and just removes a leading slash if the baseDir is not given.
  
  It does not take into account symlinks (for now).
  
  @param {string} filepath  Path to convert to relative path.  If already relative,
  it will be assumed to be relative to process.cwd(),
  converted to absolute, and then processed.
  @param {string} [baseDir] Absolute base directory to resolve the filepath from.
  If not provided, all this function will do is remove
  a leading slash.
  @returns {string} Relative filepath
