*
* NOTE: The implementation of this function currently is currently
* approximate: to do it correctly, we would need a separate implementation
* for every package manager, to query its installed version (either that, or we
* would code to query `package-lock.json`, `yarn.lock`, etc...).
*
* Instead, we will look at `package.json`, and assume that the versions
* picked by the package manager match ~that. This will work well enough for
* major version checks, but may fail for point versions.
*
* What we SHOULD do is: `actualVersion ∈ checkRange`.
*
* What we do instead is a slightly more sophisticated version of
* `requestedRange ∩ checkRange != ∅`. This will always give a correct result if
* `requestedRange ⊆ checkRange`, but may give false positives when `checkRange
* ⊆ requestedRange`.
*
* May return `undefined` if the question cannot be answered. These include the
* following cases:
*
* - The dependency is requested via local file dependencies (`file://...`)
* - The dependency uses an other type of URL, such as a GitHub URL
* - The dependency is not found in the `package.json`, such as when
* bootstrapping from an external projen package, and the `package.json`
* file only has that one external package as a dependency
*
* Otherwise it will return `true` if the installed version is probably in the
* requested range, and `false` if it is probably not.
*
* This API may eventually be added to the public projen API, but only after
* we implement exact version checking.

* @param checkRange A particular version, or range of versions.
