Added Unit tests & Coded UI Tests for Sorting Recordsets + Recordset fields

Added Unit Test (Sort_ScalarCollection) and Coded Ui test (Sort_Variable_List_Aphalbetivally)

Steps performed testing the Escape Charecters Functionality
Using JavaScript

1. Test1
   Assign [[Value1]] = "C:\test" (including the quotation marks)
   On the Script tool's Escape sequence in variables the CheckBox is ticked
   On the Script tool's _Script Syntax _ I typed return "the path is : " + [[Value1]]
   Execution result is "the path is : C:\test"

1. Test2
   Untick Escape sequence in variables
   Execution result is "the path is : C: est"

1. Test3
   Change the script content to include more escape sequences
   Tick Escape sequence in variables
   I typed return "the path is \n " + [[Value1]]
   Execution result is "the path is
   C:\test"

1. Test4
   Change the script content to include more escape sequences
   UnTick Escape sequence in variables
   I typed return "the path is \n " + [[Value1]]
   Execution result is "the path is
   C: est"

Please check the attached (Scritps used to test the Include functionality)
rubySource.rb pythonFile.py endsWith.js startsWith.js

Steps performed:
Using JavaScript

1. Test1

• On the Script tool's _Script Syntax _ I typed return "testString".endsWith("g");
• Execution results to an Error
• I clicked include file and included (endsWith.js)
• Execution result returns "True"

You can also attach multiple scripts
Repeat #Test1
now, type: return "testString".startWith("t");

• Execution results to an Error
• I clicked include file and included (startWith.js)
• Execution result returns "True"

Same procedure applied when testing the rest of the script types (The other script types I used Numbers to test a GreaterThan function)
