Manages Asterisk extensions.

It implements the complete module interface and uses meta-data provided by the account modules for its functions.
Location and naming of modules
All LAM modules are placed in lib/modules/ and are named ".inc". E.g. if you create a new module and its class name is "qmail" then the filename would be "qmail.inc". The class name of a module must contain only a-z, A-Z, 0-9, -, and _.
You can avoid to override many functions by using get_metaData().
All module classes should extend the baseModule class.

    get_pdfFields() : array

Inherited

Calling this method does not require the existence of an enclosing accountContainer.
This method must be overwritten in case that there are non static values to be returned. The $this->meta['PDF_fields'] array may be used for static content.
Format of returned hashtable:
This function uses XML formatted commands to define the PDF output. Each part in the PDF document is surrounded by "" and "".
Inside the tags there are different ways to format the output:

- simple line with attribute name and value: attribute name attribute value
- table: attribute name
  value value
  value value

Special commands:

- Alignment in : You can specify the alignment in tags with align=(L|R|C) (e.g. )
- Cell width: allows an attribute "width" to set the cell width (e.g. or ).
- Line breaks: Line breaks can be specified by adding a <
  > tag. The new line will start at the left border of the PDF document.

Examples:
Simple name+value lines:
In most cases you will just want to display a single line per attribute with its name and value.
'myAttribute' => 'AttrName 12345'
This will give the following PDF output:
Attribute name: 12345
Multiline values:
Sometimes you have multivalued attributes where it is not applicable to write all values in one line but where you want to list your values one below the other or show a table. This can be done by using the tag.
This example only uses one column but you can just use more tags per tag to display more columns.
'myAttribute' => 'AttrName

123
456
789
'
