Resolve and Reject now accept thenables

This feature is not tested by the A+ spec but is very useful, especially for creating extended library methods.

Truly Passing A+ Spec

This is the official debut of Potential as a fully compliant Promises/A+ library.

Although all 872 specs passed previously, in fact there was a rather bad bug which resulted in infinite mutual recursion when returning a rejected promise in another promise's handler function. Now fixed.

v1.2.1

1.2.1

Catch

Extends the core promises/A+ implementation with a catch function for easy error handler attachment.

Promises/A+ passing

Note: this release passed all the specs but had an infinite recursion bug that meant the compliance suite never quit. Therefore, this release did not truly pass Promises/A+.

Passing the core Promises/A+ compliance tests. Included are:

• a promise constructor Potential
  • invokes an executor function with resolve and reject parameters
  • returns a new promise
• a deferral factory function Potential.defer()
  • deferrals have resolve and reject methods (which ultimately call the settle method)
  • deferrals are each associated with a unique promise property
• promises have:
  • a .then method to add optional success & error handlers
