@Title: Convert Text From Source to Rich Text
@Type: Standard
@Author: Jane Taubman
@Version: 1.0
@Keywords: Rich Text
@LastUpdated: 27 Nov 2020
@Description: Updates Text from source for the source currently selected,  
if you have multiple sources selected all will be prompted until the process is aborted or the list is completed.  
In the first prompt select the table text, no selection will treat the whole text as a table and the delimiter, then click OK.
The results for each source will be shown in a Rich Text prompt where you can adjust as needed before clicking OK.
N.B If you have comma separated texts, the plugin will use your place records to try and identify the places. If the place is not found you will
find you have additional columns
