Added Basic Framework of Cube

[amanpalariya]

solver.py contains two classes - Cube and Rotations. Cube class stores and handles cube rotations and should contain a method get_solution by the end of the project. Rotations class contain the standard moves of a cube and some functions.

Please go through the file and understand how it works

Basic way to use this framework

from solver import Cube, Rotations

#The matrix should have shape [6, 3, 3] and can contain anything object
#Go through the image cube_net.png to understand the matrix
c = Cube(matrix) 

#Printing the net of the cube
print(c.get_string_net()) 

#This is called the sexy move by speedcubers (R U R' U')
algo = Rotations.R + Rotations.U + Rotations.R_prime + Rotations.U_prime 

#Applies the given algorithm
c.apply_algorithm(algo) 

c.print(c.get_string_net())

Algorithms can also be created as given below
algo = Rotations.algorithm_from_string("R U R' U'")

DO NOT USE NumPy TO STORE ARRAYS
If NumPy is used, swapping will fail leading to failure of rotate function
