Add a COO view method

[KyleVaughn]

Description:

Add a public method to the COO class which prints out the matrix. Depending on the standard pactices, this will either output to stdout or to a file location provided. Additional things that might be implemented as part of the standard are utalizing symetry to reduce the number of print out and that the most likely presentation is row_index col_index value

Tasks:

• [ ] Add code so the view method prints the COO matrix correctly
• [ ] Add code so the view method correclty handles all states of the matrix

Definition of done:

This task is complete when the view method is added and it agrees with the standards set for viewing the sparse matrix.

@nickamano I checked out the branch and the code looks good! I'm not sure if the assembleStorage() method is working but I successfully wrote the matrix to a file. Good work , initiate the pull request
