Put a brief note about using Alsatian to test JS code, why there is no native JS version and why you would test JS with Alsatian

Custom fail messages

3

Allow user defined failure messages to override the default Alsatian E.g. ```typescript Expect (2 + 2).toBe(5).toFailWith("you got the answer wrong"); ```

Expect should add metadata instead of throwing so that we can harvest multiple expect failures for people ** breaking change **

ACTUAL: ```console Any(Object).thatMatches("property", 42) -> {"_argumentStringifier":{},"_testers":[{},{}]}, FAIL: example test ( {"_argumentStringifier":{},"_testers":[{},{}]}) ``` EXPECTED: ``` FAIL: example test (Any Object and with property 'property' equal to '42') ```
