Adding intellij to the list of ignores
Removing unnecessary functions from commons

* These functions were useful when i had the fixed timeseries. That
  boomed, this also booms.
Removing fixed timeseries that was hiding

I dont need you, get lost!
Adding a performance package. Test Bed in place

* Adding in the initial version of the test bed:

  The Test Bed is a way to check the performance of the cache. It is a
  thread driven model with an aim to open simultaneous connections and
  to test the multithreaded nature of the Cache.

  The test bed is completely parameterized.

  As of now, The Test bed does 2 functions:
    - perform an ALLOC on a given no. of timeseries with a given set of points
    - perform a GETALL using a no. of clients to get the entire
      timeseries

  Initial observations seem "ok". Nothing very cool. Although, it seems
  like if i have about 10,000 connections, with a threadpool size of 10
  then we run into the problem where the server sends an RST to some
  clients. Though, increasing the threadpool size to 20 seems like it
  fixed the problem.

* Adding some utils class to the performance section to have some common
  functions there
* Moving some older functions from "core" here.
All methods in the cache engine are syncronized!

in lieu of Multi-Threaded support
Commons can generate a random integer now
Adding time to log of each request

Each call now logs the time it took to process that request
