✨ Initial commit for branch "dev_duncan_duncan" (ndi v0.1.6.9008) (#25)

* Added `duncan_duncan()` function to compute the aspatial racial or ethnic Relative Centralization (*RCE*) based on [Duncan & Duncan (1955b)](https://doi.org/10.1086/221609) and [Massey & Denton (1988)](https://doi.org/10.1093/sf/67.2.281)
* Added examples to README and vignette
* Formatted NEWS, grouped thematically

 ### New Features

+#### New Functions
 * Added `duncan_cuzzort()` function to compute the aspatial racial or ethnic Absolute Centralization (*ACE*) based on Duncan, Cuzzort, & Duncan (1961; LC:60007089) and [Massey & Denton (1988)](https://doi.org/10.1093/sf/67.2.281)
 * Added `hoover()` function to compute the aspatial racial or ethnic Delta (*DEL*) based on [Hoover (1941)](https://doi.org/10.1017/S0022050700052980) and Duncan, Cuzzort, & Duncan (1961; LC:60007089)
 * Added `james_taeuber()` function to compute the aspatial racial or ethnic Dissimilarity Index (*D*) based on [James & Taeuber (1985)](https://doi.org/10.2307/270845)
 * Added `lieberson()` function to compute the aspatial racial or ethnic Isolation Index (_xPx\*_) based on Lieberson (1981; ISBN-13:978-1-032-53884-6) and and [Bell (1954)](https://doi.org/10.2307/2574118)
 * Added `theil()` function the aspatial racial or ethnic Entropy (*H*) based on Theil (1972; ISBN:978-0-444-10378-9) and [Theil & Finizza (1971)](https://doi.org/110.1080/0022250X.1971.9989795)
 * Added `white_blau()` function to compute an index of spatial proximity (*SP*) based on [White (1986)](https://doi.org/10.2307/3644339) and Blau (1977; ISBN-13:978-0-029-03660-0)
-* Thank you for the feature suggestions, [Symielle Gaston](https://orcid.org/0000-0001-9495-1592)
-* Added `geo_large = 'place'` for census-designated places, `geo_large = 'cbsa'` for core-based statistical areas, `geo_large = 'csa'` for combined statistical areas, and `geo_large = 'metro'` for metropolitan divisions as the larger geographical unit in `atkinson()`, `bell()`, `bemanian_beyer()`, `duncan()`, `duncan_cuzzort()`, `hoover()`, `james_taeuber()`, `lieberson()`, `sudano()`, `theil()`, and `white()`, `white_blau()` functions.

+#### New Function Capabilities
+* Added `geo_large = 'place'` for census-designated places, `geo_large = 'cbsa'` for core-based statistical areas, `geo_large = 'csa'` for combined statistical areas, and `geo_large = 'metro'` for metropolitan divisions as the larger geographical unit in `atkinson()`, `bell()`, `bemanian_beyer()`, `duncan()`, `duncan_cuzzort()`, `duncan_duncan()`, `hoover()`, `james_taeuber()`, `lieberson()`, `sudano()`, `theil()`, and `white()`, `white_blau()` functions.
 * Added census block group computation for `anthopolos()` by specifying `geo == 'cbg'` or `geo == 'block group'`
 * Added `holder` argument to `atkinson()` function to toggle the computation with or without the Hölder mean. The function can now compute *A* without the Hölder mean. The default is `holder = FALSE`.
 * Added `crs` argument to `anthopolos()`, `bravo()`, and `white_blau()` functions to provide spatial projection of the distance-based metrics
 * The `gini()` function now computes the aspatial racial or ethnic Gini Index (*G*) based on [Gini (1921)](https://doi.org/10.2307/2223319) as the main outcome. Arguments `geo_large`, `geo_small`, `subgroup`, and `omit_NAs` were added and argument `geo` was deprecated. The `gini()` function still retrieves the original output of the aspatial income Gini Index (*G*) at each smaller geography and is moved from the `g` output to `g_data` output.
 * Specifying census block groups in `geo` or `geo_small` arguments is now `'block group'` or `'cbg'` to match internal `get_acs()` function from the [tidycensus](https://CRAN.R-project.org/package=tidycensus) package
 
 ### Updates
+
+#### Bug Fixes
 * `bell()` function computes the Interaction Index (Bell) not the Isolation Index as previously documented. Updated documentation throughout.
 * Fixed bug in `bell()`, `bemanian_beyer()`, `duncan()`, `sudano()`, and `white()` functions when a smaller geography contains n=0 total population, will assign a value of zero (0) in the internal calculation instead of NA
 * Fixed bug in `atkinson()` function to properly compute the income Atkinson Index
 * Renamed *AI* as *A*, *DI* as *D*, *Gini* as *G*, and *II* as _xPy\*_ to align with the definitions from [Massey & Denton (1988)](https://doi.org/10.1093/sf/67.2.281). The output for `atkinson()` now produces `a` instead of `ai`. The output for `duncan()` now produces `d` instead of `ai`. The output for `gini()` now produces `g` instead of `gini`. The output for `bell()` now produces `xPy_star` instead of `II`. The internal functions `ai_fun()`, `di_fun()` and `ii_fun()` were renamed `a_fun()`, `ddd_fun()` and `xpy_star_fun()`, respectively.
+* 'package.R' deprecated. Replaced with 'ndi-package.R'
+
+#### New Dependencies
 * `tigris` and `units` are now Imports
-* Reformatted functions for consistent internal structure

 * Consolidated DESCRIPTION
+* Reformatted functions for consistent internal structure
 * Re-formatted code and documentation throughout for consistent readability
 * Renamed 'race/ethnicity' or 'racial/ethnic' to 'race or ethnicity' or 'racial or ethnic' throughout documentation to use more modern, inclusive, and appropriate language
 * Updated documentation about value range of *V* (White) from `{0 to 1}` to `{-Inf to Inf}`
-* Split up vignette into three separate vignettes: 'ndi1', 'ndi2', and 'ndi3' for the *NDI*, racial or ethnic residential segregation, and additional socioeconomic disparity indices, respectively
