Estimating cross-sectional incidence Point and variance estimators for cross-sectional incidence.
`estSnapshot()`	Snapshot estimator and variance (Kaplan and Brookmeyer 1999)
`estAdjusted()`	Adjusted estimator and variance (Kassanjee et al. 2012)
`estEnhanced()`	Get enhanced estimate and variance (Bannick and Gao 2023+). This is an estimator similar to the adjusted estimator, but including optional prior HIV test results.
Obtaining recent infection testing algorithm Functions for obtaining recent infection data from a recent infection assay algorithm
`cephia`	CEPHIA Public Use Dataset
`downloadCephia()`	Download latest CEPHIA dataset
`getRitaOptions()`	See which recency assays are available by HIV subtype
`createRitaCephia()`	Create a dataset based on an algorithm and CEPHIA recency testing data.
Estimating recency assay parameters Functions for estimating test recent function characteristics
`estRitaProperties()`	Estimate a phi function, and output omega
`integratePhi()`	Integrate a phi function to calculate the MDRI or window period
Simulating datasets Functions for simulating datasets
`getTestRecentFunc()`	Approximate test-recent function with given window and shadow period
`getTestRecentFuncAdj()`	Generate a test-recent function that has a desired window and shadow period that satisfies the shape assumption of the adjusted estimator.
`simCrossSect()`	Simulates cross-sectional data based on epidemiological parameters.
`simPriorTests()`	Generates prior testing data for positive subjects based on a prior testing distribution and prior testing probability
`simExternal()`	Function to simulate studies that mimic the infection duration data from Duong et al. 2015 (or another external dataset)
