- Issue reports should be **clear**, **concise** and **reproducible**. Check to see if your issue has already been resolved in the [master]() branch or already reported in Chai's [GitHub Issue Tracker](https://github.com/chaijs/chai/issues).
- Pull Requests must adhere to strict [coding style guidelines](https://github.com/chaijs/chai/wiki/Chai-Coding-Style-Guide).
- In general, avoid submitting PRs for new Assertions without asking core contributors first. More than likely it would be better implemented as a plugin.

* Assertion Constructor
*
* Creates object for chaining.
*
* `Assertion` objects contain metadata in the form of flags. Three flags can
* be assigned during instantiation by passing arguments to this constructor:
*
* - `object`: This flag contains the target of the assertion. For example, in
* the assertion `expect(numKittens).to.equal(7);`, the `object` flag will
* contain `numKittens` so that the `equal` assertion can reference it when
* needed.
*
* - `message`: This flag contains an optional custom error message to be
* prepended to the error message that's generated by the assertion when it
* fails.
*
* - `ssfi`: This flag stands for "start stack function indicator". It
* contains a function reference that serves as the starting point for
* removing frames from the stack trace of the error that's created by the
* assertion when it fails. The goal is to provide a cleaner stack trace to
* end users by removing Chai's internal functions. Note that it only works
* in environments that support `Error.captureStackTrace`, and only when
* `Chai.config.includeStack` hasn't been set to `false`.
*
* - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
* should retain its current value, even as assertions are chained off of
* this object. This is usually set to `true` when creating a new assertion
* from within another assertion. It's also temporarily set to `true` before
* an overwritten assertion gets called by the overwriting assertion.
*
* - `eql`: This flag contains the deepEqual function to be used by the assertion.
