Oustanding `R CMD check` warnings.

[Jason Vander Heiden]

This documentation actually exists. Not sure what's up:

* checking for missing documentation entries ... WARNING
Undocumented S4 classes:
  ‘Baseline’ ‘RegionDefinition’ ‘TargetingModel’
All user-level objects in a package (including S4 classes and methods)
should have documentation entries.

Resolved following warning by exporting individual seqinr functions:

* checking dependencies in R code ... WARNING
'library' or 'require' call not declared from: ‘seqinr’
'library' or 'require' call to ‘seqinr’ in package code.
  Please use :: or requireNamespace() instead.
  See section 'Suggested packages' in the 'Writing R Extensions' manual.

Did you forget to push? I still see this when running check:

* checking dependencies in R code ... WARNING
'library' or 'require' call not declared from: ‘seqinr’
'library' or 'require' call to ‘seqinr’ in package code.
  Please use :: or requireNamespace() instead.

#' @aliases      SomeClass
#' @exportClass  SomeClass
