Add Array Relational Operator Documentation
Hi folks, I have been trying to figure out how to use relational operators with Arrays only to find there is no documentation generated for these operators. The question I originally set out to answer was what is the return type of the following function:
```
auto RelationalTest(const Eigen::Array<T, Rows, Cols>& data)
return data >= T{};
}
```
And I found a total lack of documentation that the relational operators even exist. These relational operators should be added to the catalog of coefficient-wise math functions.
