A few inconsistencies in JSDoc formatting have been fixed throughout the project. Many issues remain; these were just the few things that were easy to fix with a regular expression. The changes include: * Using lower-case for primitive types, but capitalizing non-primitive types * Separating the parameter identifier and the description with a dash * Omitting a dash between the return type and the return description * Ensuring the parameter type is first and the identifier is second (in a few places it was backwards) * Using square brackets to denote when a parameter is optional, rather than putting "(optional)" in the parameter description * Including a type and identifier with every parameter * Fixing inconsistent spacing, except where it's used for alignment * Remove incorrectly formatted `@deprecated` tags that reference non- existent properties * Remove lone comment block without accompanying function Additionally, one parameter was renamed for clarity.
