given a property name, calculates if this property name matches this nested projection item, eg.
<ul>
<li>this is a *, so it matches any property name</li>
<li>the field name for this projection item is the same as the input property name</li>
<li>this item has a wildcard and the partial field is a prefix of the input property name</li>
</ul>

@param propertyName

@return
given a property name calculates if this property name matches this nested projection item eg . <ul > <li > this is a * so it matches any property name< / li > <li > the field name for this projection item is the same as the input property name< / li > <li > this item has a wildcard and the partial field is a prefix of the input property name< / li > < / ul >
