Update Residential_Seg_Indices.md

I changed some variable names to standardized ones. This work is a part of updating metadata files for the 2.0 release.

 ### Data Limitations:
-The three indices measuring  residential segregation included here represent two categories of measures of residential segregation: measures of evenness (dissimiliarity) and measures of exposure (interaction and isolation). Three additional categories of residential segregation measurements described by Massey and Denton (1998) include measures of concentration, centralization, and clustering. Read more on the indices and their expressions from the [U.S. Census Bureau](https://www.census.gov/topics/housing/housing-patterns/guidance/appendix-b.html).

 ### Comments/Notes:
-From the [U.S. Census Bureau](https://www.census.gov/topics/housing/housing-patterns/guidance/appendix-b.html), on Measures of Residential Segregation: "Massey and Denton (1988) used an extensive literature search and cluster analysis to identify 20 different indexes of segregation and classify them into five key dimensions of segregation. Basically, evenness involves the differential distribution of the subject population, exposure measures potential contact, concentration refers to the relative amount of physical space occupied, centralization indicates the degree to which a group is located near the center of an urban area, and clustering measures the degree to which minority group members live disproportionately in contiguous areas.""

 Note: In all of the calculations, non-Hispanic whites are considered the "majority" (reference) population.
