 The file [`modules.py`](modules.py) contains the classes `Module` and `Matrix`.
 A module is a generalisation of a vector space, where the field

 need the module with the ring $R_q$ as described above. 
 
 `Matrix` allows elements of the module to be of size $m \times n$

+For Dilithium, we need vectors of length $k$ and $l$ and a matrix

 As an example of the operations we can perform with out `Module`
 lets revisit the ring from the previous example:
