A two dimensional array exercise from Cyrus Adkisson's Solidity walkthrough

Frontier EraVerified Source

Historical Significance

The 2D array chapter of cyrusadkisson/solidity-baby-steps, reading a value out of a nested fixed array by column and row. This is the same getValue shape that later became getElevation in the Etheria map storage contracts. Deployed 12 September 2015 and later destroyed.

Context

Frontier era deployment by Cyrus Adkisson, from his Solidity teaching repository.
