017ff5f8f8 Implement lazy allocation of data for complex escher properties 
This may reduce memory usage if the content is never used
or not populated for some reason.

ChartEx (new charts introduced in Office 2016) will raise exceptions in underlying XML parsing, we catch them here in order to still be able to load the document

* spacing

some extra spaces were unbearable and could have prevented the pull request

* add test

Fix NPE in XWPFParagraph.getCTSpacing(). (#950) 
We recently changed the getters so they don't create the PPr object if
it doesn't exist, but we missed adding one null check for the new
situation.

Add a test to exercise all the getters in a case where there isn't a PPr
object.

Support all possible alignment values for docx tables. (#848) 
Besides the start/center/end values specified in the OOXML standard,
Word also uses "left" and "right" as values. We need to support this
to prevent POI code from crashing with such documents.

Add getters and setters for XWPFTable indentation. (#843) 
* Add getters and setters for XWPFTable indentation.

The element tblPr->tblInd represents "table indent from leading margin".
It specifies the indentation which shall be added before the leading
edge of the current table in the document (the left edge in a
left-to-right table, and the right edge in a right-to-left table). This
indentation should shift the table into the text margin by the specified
amount.

This value is specified in the units applied via its type attribute. Any
width value of type pct or auto for this element shall be ignored.

If this element is omitted, then the table shall inherit the table
indentation from the associated table style. If table indentation is
never specified in the style hierarchy, no indentation shall be added to
the parent table. If the resulting justification on any table row is not
left, then this property shall be ignored.

To implement this property, we included a getter and a setter for the
property value, and another couple of getter/setter for the existence
(and validity) or absence of the property itself, for clients to know
they must fall back to the table style.

* Address reviewer comments.

Allow null values in XWPFParagraph.get/setAlignment(). (#829) 
* Allow null values in XWPFParagraph.get/setAlignment().

A null value in this field would indicate that the paragraph should
follow the alignment provided by the style hierarchy.

Fixes: https://bz.apache.org/bugzilla/show_bug.cgi?id=69720

* Revert getAlignment() and implement isAlignmentSet() instead.

* Replace test case file.

* Implement XWPFParagraph.getTCPPr(create).

It lets the caller choose if a new PPr should be created in case it
doesn't exist.

* use getCTPPr(boolean)

* compile issue
