getCqItanal

helper function to return list of lists, each list relates to one
generalised item from an ACER ConQuest <code>itanal</code> output.
Each list contains: (1) item-total and item-rest correlations ....

Extends 'ACER ConQuest' through a family of functions
designed to improve graphical outputs and help with advanced analysis
(e.g., differential item functioning). Allows R users to call
'ACER ConQuest' from within R and read 'ACER ConQuest' System Files
(generated by the command `put` <https://conquestmanual.acer.org/s4-00.html#put>).
Requires 'ACER ConQuest' version 5.40 or later.
A demonstration version can be downloaded from <https://shop.acer.org/acer-conquest-5.html>.

getCqItanal function

<dl><dt>sysFile</dt>
<dd>An ACER ConQuest system file.</dd>
<dt>matrixPrefix</dt>
<dd>The name of the itanal analysis defined in ACER ConQuest.
For example, in ACER ConQuest syntax <code>itanal ! matrixout = itan, ... ;</code>
the value of <code>matrixPrefix</code> is "itan".
Note, this is required as an ACER ConQuest system file can contain outputs
from several calls to itanal. A common use, for example, is to call itanal
for an overall analysis, and a second call to itanal for group-level
analysis.</dd>
<dt>isDebug</dt>
<dd>A boolean to toggle on or off debug output</dd></dl>
