Python Tech Challenge

The challenge is to create a program that computes some 
basic statistics on a collection of small positive integers. You 
can assume all values will be less than 1,000.

Implement this challenge in whatever programming language 
best highlights your skills. Also, please supply a README with 
details on how to setup and run your application

Requirements

The DataCapture object accepts numbers and returns an object for querying
statistics about the inputs. Specifically, the returned object supports
querying how many numbers in the collection are less than a value, greater
than a value, or within a range.
Here’s the program skeleton in Python to explain the structure:
capture = DataCapture()
capture.add(3)
capture.add(9)
capture.add(3)
capture.add(4)
capture.add(6)
stats = capture.build_stats()
stats.less(4) # should return 2 (only two values 3, 3 are less than 4)
stats.between(3, 6) # should return 4 (3, 3, 4 and 6 are between 3 and 6)
stats.greater(4) # should return 2 (6 and 9 are the only two values greater 
than 4)

Challenge conditions:

> You cannot import a library that solves it instantly
> The methods add(), less(), greater(), and between() should have constant time O(1)
> The method build_stats() can be at most linear O(n)
> Apply the best practices you know
> Share a public repo with your projec

Testing:

The test_data_capture.py file has the tests for all the methods of the data_capture file.

Run the follow thess steps
1. open new terminal
2. in the Python shell execute the command: python test_data_capture.py

Running the challenge code.

The data_capture.py file has the code to resolve the challenge

Run the follow thess steps
1. open new terminal
2. execute the command python
2. in the Python shell execute these commands: 
    >>> from data_capture import DataCapture
    >>> capture = DataCapture()
    >>> capture.add(3)
    >>> capture.add(4)
    >>> capture.add(3)
    >>> capture.add(9)
    >>> capture.add(6)
    >>> stats = capture.build_stats()
    >>> print(stats.less(4))
    >>> print(stats.between(3,6))
    >>> print(stats.greater(4))
