'Main method: Sub CompareAndHighlightDiffs() - this is the main/parent function that calls relevant dependencies/sub-routines.
'Description: Utility to quickly find character-by-character differences between two paragraphs/code snippets in Cells [A1] & [B1].
'Usage: In Excel spreadsheet copy-paste the two paragraphs/code snippets (that need to be compared) in Cells [A1] & [B1], then run the CompareAndHighlightDiffs() function.
'Date Created: 29-09-2017
'Date Modified: 23-10-2017
'Version: 1.2
'Version info/Change Log:
' - Added feature to span/merge multiple cells, when text overflows out of first cell.
' - Fixed issue with recognition of the repeating words.
