Boundary.rst gives wrong description for negative values

Please read: https://github.com/FINRAOS/DataGenerator/blob/master/docs/tags/DG_Boundary.rst

Seems that the negative tag repeats a subset of the positive values. Is that a mistake in the write up, or the code needs to get fixed ?

[leeny324]

That was changed after the documentation was written. Will update the doc

@jeanmusinski can you check ?

[mibrahim]

@leeny324 can you verify if that's done ?

fixed with #263
