initial implementation

Initial implementation of B+ tree.  As of now, only the find works
reliably.
finish insert method

Finished the insert method.  Need to verify that find works.  Doesn't
seem to be working very well now.
implement a binary search for nodes

the bisect module doesn't seem to like arbitrary objects.  Reimplemented
bisect.bisect in pure python  that appears to behave much better.
Small edits to fft algorithm lab and added a solutions file.
Made changes to shorten the fft algorithm lab.  Added fft labs to Vol2.
Added solution files to both 1d fft labs.
Added in an empty lab for wrapping C and C++ code.
Description of .o, .so, and .dll files in cwrap lab.
Lab: Statistical Distributions

Review common distributions in statistics.

Merge branch 'btree' of github.com:ayr0/numerical_computing into btree
move lab to proper folder

This is an Algorithms lab.
Merge branch 'develop' into fft
Lab: Balanced Trees

Added balanced trees lab to Vol2
explain AVL balance cases

Use figures to illustrate the balancing cases for an AVL tree.  Added
problem to implement balancing on a BST (from the Data Structures lab).
