`areEqual` overloads

== Synopses

Declared in `<bdlb_bitstringutil.h>`

Return `true` if the specified low‐order `numBits` in the specified `bitString1` are bitwise equal to the corresponding bits in the specified `bitString2`, and `false` otherwise. The behavior is undefined unless both `bitString1` and `bitString2` have a length of at least `numBits`.

Return `true` if the specified `numBits` beginning at the specified `index1` in the specified `bitString1` are bitwise equal to the `numBits` beginning at the specified `index2` in the specified `bitString2`, and `false` otherwise. The behavior is undefined unless `bitString1` has a length of at least `index1 + numBits` and `bitString2` has a length of at least `index2 + numBits`.
