[Pine] Support PineTopper as a component of distkv ecosystem.

[jovany-wang]

Introduction

As discussed before, we'd like to support a feature named Pine as the ecosystem of Distkv. The Pine is a set of useful components for Web application that helps Web developer develop simpley.

This PR supports the PineTopper component as the ranking list.

Usage of this PR

The usage or API of PineTopper looks like:

try {
  Pine.init();
  PineTopper topper = Pine.newTopper();
  topper.addMember("Bob", 80);
  topper.addMember("Allen", 90);
  topper.addMember("Lisa", 100);

  // This didn't implement in this PR now.
  topper.getMember("Bob").incr(20);

  topper.top(2); // will return the top 2 items: Bob, 110         Lisa 100
 
} catch (Exception e) {

} finally {
 Pine.shutdown();
}

The related issue is #279

[kairbon]

Can We add an method called like getMemberInfo.
For example:

v =  topper.getMemberInfo("hello");
print( v. getRank() );
print( v. getScore() );
