Hi @zmalatrax

Fixed the documentation and the program comparison. I changed the PR to ready for review but if there's any modification needed please let me know.

[zmalatrax]

good, just some details on the JSDoc :)

Good job

Found a Cairo program using the TestLessThanOrEqual hint

[zmalatrax]

We've previously talked about the fact that Cairo 2.7.0 doesn't use the TestLessThanOrEqual hint when doing arithmetic comparisons. I said that we could let the Cairo programs as is, and use an older version of the compiler to test it, until we find a Cairo program that uses it for the latest Cairo version.

I've found a Cairo libfuncs that uses the TestLessThanOrEqual hint, so it can be tested with Cairo 2.7.0 :)

Note: After further thinking, if the latest Cairo version doesn't use a specific hint for one operation, another program should be written, using another operation that still uses this hint, not defaulting on "using a previous Cairo version".
