Cyrk

Bug Fixes:
- `nbrk_ode` fixes
- Improved the storage of results during integration, greatly reducing memory usage. This provides a massive increase in performance when dealing with large time spans that previously required the processor to search outside its cache during integration.
- This fixes [issue 5](https://github.com/jrenaud90/CyRK/issues/5).

Performance Improvements
- Various improvements to `nbrk_ode` make it about 200% faster on small time-spans and over 30x+ faster on large timespans.
- Improvements to `cyrk_ode` provided a modest (~5%) performance increase.

Other Changes
- Helper functions now have an additional optional kwarg `cache_njit` which is set to `False` but can be toggled to enable njit caching.
- Fixed issue in function timing calculation used in the benchmark plot.

Bug Fixes
- Fixed issue in precompiled wheel distribution ([issue 9](https://github.com/jrenaud90/CyRK/issues/9)). (Fix made by [Caroline Russell](https://github.com/cerrussell))

Other Changes
- Updated CI workflows to utilize `cibuildwheel` for building binary wheels.

2022

Bug Fixes
- `cyrk_ode` fixes
- Bug in doubling up on the time step in the final inter-step diffeq calculation.

Other Changes
- Added a performance tracking package to measure CyRK's performance over time and versions.

New Features
- Added helper functions `from CyRK import nb2cy, cy2nb` which convert differential equation argument signatures between the formats required for cyrk and nbrk ode solvers.

Other Changes
- Added back some commented out tests that were left over from the bug fixed in v0.2.0.
- Added tests to check that performs both cyrk and nbrk integrations on larger time domains.
- Removed the specific test that looked at the underlying issue fixed in v0.2.0 (this is still checked by other tests).

Bug Fixes
- Fixed issues with the metadata provided by pyproject.toml.
- `cyrk_ode` fixes
- Fixed bug that was causing the ubuntu slowdown and likely other errors
- Added a `cabs` absolute value function to ensure that complex numbers are being properly handled when `abs()` is called.
- `nbrk_ode` fixes
- Fixed warning during numba integration about contiguous arrays.
- Fixed issue where variable was referenced before assignment when using nbrk's DOP853

Performance Improvements
- `cyrk_ode` improvements
- Integrator now selects an output message based on the status code rather than building a string during the integration loop.
- Switched the loop order for the final list to ndarray conversion. Before the time domain was being redundantly built y_size times.

Other Changes
- pyproject.toml provides more constrained package list rather than an open search.
- Added back ubuntu tests and publishes to GitHub workflows.
