func_documentation_string: Used when composing a function that needs to operate on the first character found and needs to
  return the original string with the modified character within it.
  @see sjl.lcaseFirst or sjl.ucaseFirst (search within this file)
  @param str {String} - string to search for first alpha char on
  @param func {String} - function to run on first alpha char found; i.e., found[func]()
  @param thisFuncsName {String} - the function name that is using this function (in order
  to present a prettier error message on `TypeError`)
  @throws {TypeError} - If str is not of type "String"
  @returns {String} - composed string
