Signatory

-----

-----

-----
Added a logo! (Very exciting!)
Slightly improved the speed of forward signature computations on the CPU.
Moderately improved the speed of backward signature computations on the CPU.
Added the 'remember_path' option to Path.
Deprecated the max_parallelism function. It was a bad idea.
Added the 'parallel' and 'save' options to the benchmarks.

-----
Dramatically improved the speed of several calculations.
Added logsignature calculations to Path.
Added the signature_to_logsignature function.
Added the multi_signature_combine function.
Added the max_parallelism function.
Improved speed and stability of the backwards operation through Path.
Added (fixed) memory benchmarking

-----
Tweaks to be able to compile on different platforms.
Prebuilt wheels are now available via PyPI! (Making PyPI happy is the real reason this is a whole 'nother release.)

-----
Added signature_combine
Added the new optional argument 'initial' to signature and Signature.
Expanded the functionality of Path, in particular to allow updating it, and to be able give the signature of the whole
path cleanly.
Updated documentation with more examples, a clearer layout, and a few custom pieces of CSS to aid clarity.
