Better support of doing fitting or peak analysis (including related gadgets) on Y offset plot.

In the past, if user plot stacked lines with Y offset and then do fitting, the fitted curves are not stacked and stay with original plot.

Improved in Origin 2019b.

Improve Statistics results for some special NLFit types

For Nonlinear Multiple Dependent Variables Fitting, ANOVA table is improved.

Before 2019b, ANOVA table in the report only shows the results for the first dataset(Dataset B in the following case). Now the result is improved and similar to Global Fit's result, DF and TSS should be total data.

For the Nonlinear Fitting using Orthogonal Distance Regression, R-Square quantity is improved.

Before 2019b, R-Squared value may always be 1 though the ODR fit is normal. It is caused by the inappropriate TSS. Now the R-Square should be more accurate as TSS calculation is improved as:

TSS = sum( (y - ymean)^2) + sum( (x - xmean)^2)
R^2 = 1 - RSS/TSS
where TSS is the total sum of square, and RSS is the residual sum of square.

Reset all dialog custom positions on new Origin session

There are cases user moved some dialog, script window, etc. to other location .e.g. another monitor and when restarting Origin, user couldn't find them.

So in Origin 2019b, by default the dialog locations will reset.

Set System variable @RDP=0 to go back to old behavior.

JIRA	SUMMARY	DETAILS
ORG-19433	Improvements on IF() and IFNA() functions	Fixed if(C=0,A,"") and C==0? A:"" issue of only filling 1st occurance of true condition. Default else to blank. E.g. fill column A with 1, 2, 3 and enter if(A=2,100) in column B's F(X), row 1 and 3 should be blank values instead of missing. IF() supports both numeric and string return. E.g. if(A<5,"small","big") works. In 2019, user needs to type if(A<5,"small","big")$
ORG-19719	LabTalk command to clear imported data	del -di: Delete imported data in current sheet
ORG-19715	LabTalk string function improvements	IsEmpty() will give 1 for range out of bound. E.g. column A has text in 1st 4 rows only. In column B, enter formula IsEmpty(A) for rows from 1 to 10. row 5-10 will be filled with 1. When concatenating two string columns, use longest data to set the range. E.g. if there are 5 rows of data in column A, while 10 rows of data in column B. Set column C's formula as A$+B$. Origin uses the 1st vector to decide the calculation range so only 1st 5 rows was conconcated. Origin 2019b, usea the longest rwo to decide range. To go back to old behavior, which used the first vector i2, set @VAS=0
ORG-18180	Multi-sheet range support	This is supported in many tools that supports multi-sheet range. E.g. if user wants to do statistics in same range of data on multiple sheets, user can specify the input as [book1](1:5)!1[89]:17[95] If it's not consecutive sheets, then what should be the syntax, (1, 3:5)! together with options in Input node "Combined as Single Dataset", user can get statistics of same range in different sheets easily.
ORG-19284	New Object is wbook but can be abbreviated as wbk
ORG-19719	New Switch for DOC command	doc -rn: Make current project as Untitled and new project doc -e WM: Execute for all workbooks and matrix books in the project doc -e LBC: Execute for all sheets on book with Data Connector
