* @author Arnia Sowftare
* @brief Models the <table> tag inside an XML Query file
*
* @abstract
* Example
* <table name="modules" />
* <table name="documents" alias="doc" />
* Attributes
* name - name of the table - table prefix will be automatically added
* alias - table alias. If no value is specified, the table name will be set as default alias
* join_type - in case the table is part of a join clause, this specifies the type of join: left, right etc.
* - permitted values: 'left join','left outer join','right join','right outer join'
* Children
* Can have children of type <conditions>
