MOD LOG:
    200707171110
        Changed ssSTRtoSQL(str) to gSTRtoSQL(str)
        Changed ssSQLtoSQL(str) to gSQLtoSQL(str)
        Changed formatDtm(dtm) to gFormatDtm(dtm)
        Added gRepeat(str, cnt)
        Changed all ss<timestuff> to g<timestuff>
        Changed Logout(lfMessage,AppID,OrgID,SubOrgID,UserID,TableName,TableID) to gLogout(lfMessage,AppID,OrgID,SubOrgID,UserID,TableName,TableID)
    200707201455 Changed gSendEmail so it can send an attachment
    200710081127 Added gHTMLEncode(str). Similar to the Server.HTMLEncode of ASP
    200802221059 Changed gSendEmail so it specifies filename of attachment. -georgelhernandez@iclops.com
    200803281545 Got better trim methods for String.prototype. -georgelhernandez@iclops.com
    200803311244 Updated gSendEmail for new Google servers and so it take obj as parameter. -george.hernandez@iclops.com
    200804041731 Added gstrEscapeJS(str). Escape a string for putting into JSON.
    200804071059 Added gMakeJSON(Rst, ColIDNeeded). Outputs ADO recordset as JSON
    200804171120 Added the AES suite and gGetEncryptionKey() as well as var gEncKey. -george.hernandez@iclops.com
    200805021304 Added gCheckSessionVariables() -george.hernandez@iclops.com
    20080606 1624 Added String.prototype.apose which takes an apostrophe (') and escapes it with an apostrophe (''). -george.hernandez@iclops.com
