Comparison operations

[Daniel-Liu-c0deb0t]

More comparison operations can be implemented and sped up using vector operations.

• == (basic version available in src/utils)
• <
• <=

The order can be pretty arbitrary; its just that some consistent order has to exist to allow sorting and binary search tree operations to be well-defined.

More I think on nuc2bit more I think we need to create a type to store the 2 bit representation of nucleotide.

Maybe we can use or by inspired by bv or bitvec

[Daniel-Liu-c0deb0t]

That is a very good point. It allows the internal representation, which is a contiguous piece of memory, to be manually managed (special alignment and padding) for maximum efficiency, so allocations do not have to be done for every operation. It should be easier for us to manually roll a bit vector class, since we want to control the memory carefully.
