Subject: [ANN] PQueue v2.0.0 released

PQueue 2.0.0 has been released. 

A priority queue is like a standard queue, except that each inserted elements is given a certain priority, based on the result of the comparison block given at instantiation time. Retrieving an element from the queue will always return the one with the highest priority.

This is a complete rewrite to simplify the design and use more of Ruby's internal methods.  Overall performance should be markedly improved. A few method names have changed to be more consistent with Ruby's other data structure. Note that the internal heap is now in reverse order from the previous version. If using #to_a be aware that the priority order will be reversed. This release also switches the library to distribution under the BSD-2-Clause license. 

Changes: 

* Rewrite library.
* Modernize build configuration.
* Switch to BSD-2-Clause license.
