/**
* There are at least 3 approaches for replacing variables in
* a docx.
*
* 1. as shows in this example
* 2. using Merge Fields (see org.docx4j.model.fields.merge.MailMerger)
* 3. binding content controls to an XML Part (via XPath)
*
* Approach 3 is the recommended one when using docx4j. See the
* ContentControl* examples, Getting Started, and the subforum.
*
* Approach 1, as shown in this example, works in simple cases
* only. It won't work if your KEY is split across separate
* runs in your docx (which often happens), or if you want
* to insert images, or multiple rows in a table.
*
* You're encouraged to investigate binding content controls
* to an XML part. There is org.docx4j.model.datastorage.migration.FromVariableReplacement
* to automatically convert your templates to this better
* approach.
*
* OK, enough preaching. If you want to use VariableReplace,
* your variables should be appear like so: ${key1}, ${key2}
*
* And if you are having problems with your runs being split,
* VariablePrepare can clean them up.
