Develop and Apply Two-Regression Algorithms

Facilitates development and application of two-regression algorithms for research-grade wearable devices. It provides an easy way for users to access previously-developed algorithms, and also to develop their own. Initial motivation came from Hibbing PR, LaMunion SR, Kaplan AS, & Crouter SE (2018) . However, other algorithms are now supported. Please see the associated references in the package documentation for full details of the algorithms that are supported.
