Reorganize this module (and create additional) to workaround SemVer deficiencies

[JamesMGreene]

I propose that this module MUST be re-written as a new module (let's refer to it as "flexsdk" for now) in order to support SemVer while also maintaining non-prelease, FlexSDK-specific versioning.

For more background on the issue and how I arrived at the following approach, see semver/semver#242
