ColossusPoisSurv

<code>ColossusPoisSurv</code> assigns and interprets interval columns for poisson model.
This functions is called using the arguments for Poisson or Poisson_Strata in the
right-hand side of the formula. Uses an person-year column, number of events, and
any strata columns. The first two are expected to be in order or named: pyr and event.
Anything beyond the event name is assumed to be strata if Poisson_Strata is used.

Performs survival analysis using general non-linear models. Risk models can be the sum or product of terms. Each term is the product of exponential/linear functions of covariates. Additionally sub-terms can be defined as a sum of exponential, linear threshold, and step functions. Cox Proportional hazards, Poisson, and Fine-Gray competing risks regression are supported. This work was sponsored by NASA Grants 80NSSC19M0161 and 80NSSC23M0129 through a subcontract from the National Council on Radiation Protection and Measurements (NCRP). The computing for this project was performed on the Beocat Research Cluster at Kansas State University, which is funded in part by NSF grants CNS-1006860, EPS-1006860, EPS-0919443, ACI-1440548, CHE-1726332, and NIH P20GM113109.
