Resolves #13
Fixes #25

This PR changes the syntax for DocTest expectations in source code. Currently => matches the expected REPL output. With this change, => instead matches the value literal in the REPL output.

The following table documents all of the available expectations:

Code Meaning
1 + 2 // -> String assert type
1 + 2 // => 3 assert value
1 + 2 // ~> String = \d assert pattern match
1 / 0 // !! error: division by zero assert error

In addition, this PR also refactors the use of regular expression into a new Scanner type and fixes a bug in the regex pattern that caused DocTest annotations to be missed.
