delayP

This function has two behaviors:

1. Creates a promise that resolves after x milliseconds. This function is overloaded and instead of Number can also consume options object. If timeout not specified by options object, the returned promise resolves immediately.

RA.delayP(100); //=> resolves after 100 milliseconds with `undefined` value
RA.delayP({ timeout: 100, value: "val" }); //=> resolves after 100 milliseconds with `"val"` value

1. Create a promise that rejects after the specified milliseconds. This function is overloaded and instead of Number can also consume options object. If timeout not specified by options object, the returns promise rejects immediately.

RA.delayP.reject(100); //=> rejects after 100 milliseconds with `undefined` value
RA.delayP.reject({ timeout: 100, value: new Error('error') }); //=> rejects after 100 milliseconds with `Error('error')` value

This PR should serve as a model template of PR for delayP function.

I was currently using mocha grep pattern for this mocha --grep <NAME_OF_YOUR_TEST>

Yes you can also use the grep, there are multiple ways how to achieve the same.

I have implemented the function like this so it is good to go. Also should I throw a error message if argument passed by the user is not a Number or Object

Nope, we try not to validate input arguments unless absolutely necessary.

Also I am using pipe to call resolveP how can I send the value param to resolveP?

Figured it out!
