Subject: [PATCH] Create shared.js

The files in this project use functions from shared.js, which was previously missing.  SharedHelpers is defined.  This provides the following functions:
AddAntiForgeryToken
StripCurrency
StripWhitespace
ColorScale
DateTimeInit
Resizable
CaptureHtml
CaptureChart
SubstringMatcher

simpleGrid:
item[cellName] = SharedHelpers.StripCurrency($cell.text().trim());

numericTableWidget:
var numericValue = SharedHelpers.StripCurrency(SharedHelpers.StripWhitespace(value));

editableTableWidget:
source: SharedHelpers.SubstringMatcher(data)
